    OF AN EXHAUST AIR EXHAUST DEVICE
    Tf
    Invention background
    The present invention relates to the field of diving masks, and in particular the masks used for underwater hiking, also called PMT (Palmes-Masque-Tuba), in English "snorkeling".
    This underwater hiking activity allows you to observe the seabed while swimming on the surface of the water. The underwater hiker must therefore be able to keep their head underwater while breathing.
    Generally, the underwater hiker is equipped with a mask for vision, and a snorkel for breathing. The tuba consists of a tube, the lower end of which is provided with a buccal portion which is housed in the mouth of the user, and an upper end allowing both the admission of fresh air and the exhaust of expired air.
    It is known that such equipment has many drawbacks. First, because breathing through the mouth is not natural, some people find it difficult to breathe orally using a snorkel. Another disadvantage is that it is not possible to speak underwater when you have a snorkel in your mouth.
    Also, the use of this mask-snorkel device is not very comfortable. To overcome this drawback, the document FR 3 020 620 proposes a diving mask making it possible to breathe through the nose and through the mouth.
    This diving mask includes:
    a body provided with a visor and a flexible skirt, said flexible skirt comprising a partition delimiting an upper chamber for the vision of a lower chamber for breathing, the partition being arranged to be supported above the nose of the user so that the user's mouth and nose are located in the lower chamber, while the user's eyes are located in the upper chamber, the partition having at least one passage arranged to allow a flow of fresh air between the upper chamber and the lower chamber during a user inspiration phase;
    a tuba arranged in extension of an upper part of the body, the tuba comprising at least one air duct;
    wherein the body has an exhaled air exhaust device which fluidly connects the lower chamber with the air duct of the snorkel.
    This mask also comprises a snorkel provided with several channels and a plate which includes non-return valves in order to close the air outlet channels during an inspiration phase, on the one hand, and in order shut off the air intake channel during an expiration phase.
    If such a tuba gives full satisfaction to use, the manufacture of such a tuba is relatively complex and expensive.
    Subject and summary of the invention
    A first object of the invention is to propose a mask of simpler design overcoming the aforementioned drawbacks.
    The invention achieves its object by the fact that the exhaled air exhaust device comprises at least a first non-return valve arranged to allow a flow of exhaled air directed from the lower chamber towards the air duct of the snorkel during 'a user expiration phase, the first non-return valve being closed during a user inspiration phase.
    It is understood first of all that the tuba is in fluid connection with the upper chamber. To do this, the body advantageously includes a fresh air intake device which communicates fluidically with the tuba and with the upper chamber.
    Furthermore, the first non-return valve is located on the body of the mask whereas, in the aforementioned prior art, the non-return valve is located on a plate of the snorkel.
    According to the invention, the first non-return valve is arranged to close the exhaled air exhaust device during an inspiration phase.
    Furthermore, the flexible skirt is preferably fixed to the visor. In addition, the visor is at least partially transparent. Preferably, it has a transparent flat portion which is located opposite the upper chamber.
    Also, during an inspiration phase, closing the first non-return valve has the effect that the fresh air does not flow through the air exhaust device. An advantage is to avoid the inspiration of the air which has just been exhaled and which is still in the exhaled air exhaust device or in the air duct of the snorkel.
    Such an arrangement makes it possible to simplify the design and manufacture of the snorkel as soon as the first non-return valve is in the body of the mask.
    The operation is as follows.
    During a user expiration phase, the first non-return valve opens and the exhaled air can flow into the air duct of the snorkel via the exhaled air exhaust device.
    During an inspiration phase, the first non-return valve closes and the fresh air enters the snorkel then flows successively into the upper chamber and into the lower chamber where the mouth and nose are located. 'user. The first non-return valve being closed, the user does not breathe in the air that he exhaled during the previous respiratory cycle.
    Advantageously, the first non-return valve is disposed between the lower chamber and the exhaled air exhaust device. Also, the first non-return valve is disposed near the mouth and nose of the user, which makes it easier to open during an expiration phase. It is understood that the first check valve opens due to the increase in pressure in the lower chamber 52 during expiration.
    The first non-return valve can also be placed in the lower chamber.
    Advantageously, the first non-return valve is disposed in the exhaled air exhaust device. Preferably, the first non-return valve is located at a lower end part of the exhaled air exhaust device so as to be located near the lower chamber.
    Advantageously, the first non-return valve comprises a flexible membrane.
    Very preferably, the flexible membrane consists of a portion of the flexible skirt. An advantage is to limit the number of parts constituting the mask, which makes it possible to reduce the manufacturing cost.
    However, without departing from the scope of the present invention, the flexible membrane could also be an insert, distinct from the skirt.
    Advantageously, the first non-return valve comprises a valve seat cooperating with the flexible membrane, the valve seat being integrated into the visor.
    Again, an advantage is to limit the number of parts making up the mask, making it possible to further reduce the cost of manufacturing the mask.
    Preferably, the valve seat forms a single piece with the visor. Advantageously, the valve seat constitutes a part of the visor.
    According to an advantageous, but not exclusive, embodiment example, the exhaled air exhaust device comprises at least a first exhaled air exhaust channel which extends along one of the lateral edges of the visor, the flexible skirt having a first lateral part which covers the first exhaust air channel. The first air exhaust channel may consist of two adjacent ribs which protrude from an edge of the visor.
    The side part of the skirt has a side edge into which the first exhaust channel is engaged in order to prevent water from entering the first air exhaust channel. To do this, the side edge of the skirt has an upper wall and two side walls; the side walls flank the two ribs of the first exhaust channel, while the upper wall covers the first exhaust channel to ensure sealing. Furthermore, the lateral edge is located at the outer periphery of the sealing lip of the skirt which is arranged to come to bear on the face of the user.
    Preferably, the first exhaled air exhaust channel forms a single piece with the visor. More preferably, the two adjacent ribs form a single piece with the visor.
    More preferably, the valve seat of the first non-return valve consists of a portion of the first exhaled air exhaust channel.
    Preferably, the body of the mask further comprises a hoop which surrounds the visor. Preferably, the peripheral edge of the skirt is clamped between the strapping and the first exhaust channel. This has the effect of preventing the peripheral edge of the skirt from uncoupling from the first exhaust channel.
    Advantageously, the first exhaled air exhaust channel comprises a lower end portion comprising at least one opening opening into the lower chamber, and the first non-return valve is arranged to close said opening during a phase of user inspiration.
    Preferably, the flexible membrane is located inside the first exhaled air exhaust channel, opposite said opening. Furthermore, the opening is formed between portions of the first exhaled air exhaust channel which constitute the seat of the first non-return valve.
    Preferably, the lower end portion has two adjacent openings which can be closed off by the membrane of the first non-return valve. According to another variant, the first non-return valve could comprise several flexible membranes.
    Advantageously, the exhaled air exhaust device further comprises a second exhaled air exhaust channel, and a second non-return valve arranged to allow a flow of exhaled air directed from the lower chamber towards the conduit d air from the snorkel during a user expiration phase, the second non-return valve being closed during a user inspiration phase.
    The second exhaled air exhaust channel is similar to the first exhaled air exhaust channel. Also, the first and second exhaled air exhaust channels are located on each side of the mask body.
    According to another advantageous aspect of the invention, the tuba has a single air duct which is in fluid communication with the lower chamber and the upper chamber.
    An advantage is therefore to simplify the design and manufacture of the snorkel, compared with the aforementioned prior art snorkel which has three channels. Another advantage is to be able to have the entire interior volume of the tuba both during the inspiration and expiration phases, unlike the prior art where the tuba is compartmentalized into air inlet and outlet channels. This makes it possible to appreciably increase the flow of air entering and leaving compared to the mask of the prior art, which increases the comfort of use of the mask by facilitating bucco-nasal breathing.
    The single air duct is therefore in fluid communication with the expired air exhaust device, and also with the fresh air intake device. More preferably, the single air duct is in fluid communication with the first and second exhaled air exhaust channels.
    Advantageously, the partition comprises at least one non-return valve arranged to allow only a flow of fresh air directed from the upper chamber to the lower chamber during a user inspiration phase.
    It is understood that the non-return valve opens during an inspiration phase and closes during an expiration phase. The function of the non-return valve is to prevent the exhaled air from flowing towards the upper chamber, whereby the appearance of fogging on the flat part of the visor which is situated opposite the eyes of the is avoided. user.
    According to an advantageous aspect of the invention, the non-return valve comprises a flexible flap consisting of a part of the flexible skirt. Preferably, the flexible flap of the non-return valve consists of a portion of the partition. The flexible shutter is preferably delimited between a free edge of the partition and a cut made in the partition. Thanks to this cut, the flexible flap has a mobility allowing it to fold during an inspiration phase so as to open said passage.
    More preferably, during an expiration phase, the flexible flap of the non-return valve bears against the visor in order to close said passage. During an inspiration phase, the flexible flap of the non-return valve opens to allow fresh air to enter the lower chamber.
    Advantageously, the flexible skirt includes a top sleeve which surrounds the top connector of the visor. One advantage is to ensure the seal between the skirt and the connector at the top of the mask body.

    Detailed description of the invention
    In Figures IA and IB, a diving mask 10 is illustrated in accordance with the present invention.
    This diving mask comprises a body 12 intended to be positioned on the face of the user, the body 12 having an upper part 14 and a lower part 16.
    As can be understood from FIGS. 1A and 1B, the upper part 14 of the body 12 is intended to be placed close to the forehead of the user, while the lower part 16 of the body is intended to be placed close to the user of the user's chin.
    Furthermore, the diving mask 10 comprises a snorkel 18 arranged as an extension of the upper part 14 of the body 12.
    In this example, the tuba 18 is removably mounted to the body 12.
    Referring to the exploded view of FIG. 2, it is understood that the body 12 mainly consists of a visor 20 and a flexible skirt 22.
    The visor 20 is made of a rigid material, for example polycarbonate, while the flexible skirt 22 is made of a flexible material, for example of LSR silicone.
    The flexible skirt 22 is fixed to the visor.
    The body 12 also includes a hoop 24 which is shaped to surround the visor. This strapping 24 has in particular the function of ensuring, or at the very least improving, the fixing of the flexible skirt to the visor 20.
    The body 12 further comprises a chin strap 26 comprising a cover 28 which covers a lower portion 30 of the visor as well as a lower portion 32 of the strapping 24. As can be seen in FIG. 2, the lower portion 32 of the strapping 24 is split and comprises a clamping element making it possible to tighten the strapping 24 against the skirt and the visor.
    As can be seen in FIG. 1A and 1B, the strapping 24 also has slots 34 intended to receive one or more elastic straps (not illustrated here).
    As can be seen in FIG. 2, the strapping 24 has, on its internal face 25, ribs 27 which have the function of locking the skirt relative to the strapping.
    Referring to Figures IA and 3, we see that the visor 20 is shaped to cover the face of the user. The visor comprises a transparent flat portion 20a intended to be located substantially at the level of the user's eyes, and a convex portion 20b intended to be located at the level of the user's nose and mouth. In this nonlimiting example, the convex portion 20b is transparent. However, and without departing from the scope of the present invention, the curved portion 20b could be opaque or else transparent and covered with an opaque cover.
    Referring to Figures IA, IB and 2, it can be seen that the flexible skirt 22 comprises a partition 40 delimiting an upper chamber 50 for the vision of a lower chamber 52 for breathing, the partition 40 being arranged to be in contact with the above the user's nose so that the user's mouth and nose are located in the lower chamber 52, while the user's eyes are located in the upper chamber 50.
    The partition 40 is fixed to the visor 20 by an attached fixing piece which is clipped to fixing lugs 53, visible in FIG. 3, protruding from an internal face of the convex portion 20b.
    The partition has two orifices 41 which engage with the fixing lugs 53 before the positioning of the fixing part.
    The partition also has two passages 54, better visible in FIGS. 2 and 13, which are arranged to allow a flow of fresh air between the upper chamber 50 and the lower chamber 52 during an inspiration phase of the user.
    Furthermore, in this example, the partition comprises two non-return valves 56 which are arranged to allow only a flow of fresh air directed from the upper chamber 50 to the lower chamber 52 during an inspiration phase of the user.
    It is therefore understood that the non-return valves 56 have the function of closing the aforementioned passages 54 during an expiration phase of the user.
    In this example, as illustrated in FIG. 13, each of the non-return valves 56 comprises a membrane 58 consisting of a part of the flexible skirt. More specifically, in this example, each membrane 58 consists of a portion of the partition 40 of the flexible skirt.
    The mobility of the membranes 58 is obtained by the fact that the partition has two cutouts 60 which make it possible to locally detach the membrane from the rest of the partition. Thanks to these cutouts, the membranes 58 can bend and come off from the internal face of the visor, in particular during an inspiration phase, in order to open the passages, which allows fresh air to enter the lower room.
    The operation is as follows.
    During an expiration phase, the expired air has the effect of pressing the membranes 58 against the internal face of the convex portion 20b of the visor, which has the effect of closing the passages 54 and therefore preventing the the expired air passing from the lower chamber 52 to the upper chamber 50.
    During an inspiration phase, the drop in pressure which occurs in the lower chamber 52 has the effect of detaching the membranes 58 from the visor 20 and of opening the passages 54, whereby the fresh air can flow from the snorkel to the lower chamber 52 passing through the upper chamber 50.
    Referring to FIG. 7, it can be seen that the tuba 18 comprises a tubular portion 70 which has a first end 72 and a second end 74 opposite the first end 72.
    The tuba 18 also comprises a cover 76 which is mounted at the second end 74 of the tubular portion 70.
    The tubular portion 70 also has holes 78 to allow the exchange of air between the atmosphere and the mask.
    The tuba 18 also comprises a device 80 for closing the air inlet of the tuba 18 when the latter is submerged. The device 80 comprises a float 82 which is movable in translation relative to a plate 84 comprising a first orifice 86 and a second orifice 88, the first and second orifices 84 and 86 opening into an interior volume of the cover 76.
    The first orifice 86 communicates fluidically with an air duct 90 formed in the tubular portion 70 of the tuba 18, while the second orifice 88 is disposed opposite the float 82.
    The second orifice 88 is bordered by a seal 92 which conforms to cooperate with the float 82 when the tuba 18 is submerged.
    The operation is as follows.
    When the tuba 18 is out of the water, the float 82 is in the low position, so that the air can flow between the air duct 90 and the atmosphere via the holes 78 passing successively through the first orifice 86, the chamber defined inside the cover 76 and the second orifice
    88.
    When the tuba 18 is submerged, the float 82 rises to come to press against the gasket 92, which has the effect of closing the second orifice 88, as a result of which air cannot enter the duct. air 90.
    Furthermore, in this example, the tubular portion comprises a single air duct 90 which communicates with the lower and upper chambers.
    According to the invention, the body 12 also includes an exhaled air exhaust device 100 which fluidly connects the lower chamber 52 with the air duct 90 of the tuba 18.
    It is therefore understood that, during an expiration phase, the air exhaled in the lower chamber 52 flows into the exhaled air exhaust device then into the air duct 90 of the tuba 18 before leaving from the snorkel to the slots 34.
    Referring to Figure 3, the exhaled air exhaust device 100 includes a first exhaled air exhaust channel 102 which extends along a first side edge 104 of the visor.
    As can be seen in FIG. 3, the first exhaled air exhaust channel 102 extends between a lower part 20c of the visor 20 and an upper part 20d of the visor.
    The first exhaled air channel 102, in this example, consists of two adjacent ribs 106, 108 which project from a first lateral edge 20e of the visor.
    In this example, the first exhaled air exhaust channel 102 forms a single piece with the visor 20.
    The exhaled air exhaust device 100 further includes a second exhaled air exhaust channel 104, which is similar to the first exhaled air exhaust channel 102, and which also extends between the bottom 20c of the visor and the upper part 20d of the visor.
    The second exhaled air exhaust channel being similar to the first exhaled air exhaust channel, in the following description only the first exhaled air exhaust channel will be described.
    The upper part 20d of the visor further comprises a summit connector 106, which forms a single piece with the rest of the visor, and which comprises a central conduit 108, a first lateral conduit 110, and a second lateral conduit 112.
    The central duct 108 communicates fluidically with the upper chamber 50, while the first central duct 110 communicates fluidically with the first exhaled air outlet channel 102, while the second lateral duct 112 communicates fluidly with the second exhaust duct of expired air 104.
    As can be understood with the help of FIG. 3, the first exhaled air exhaust channel 102 and the second exhaled air exhaust channel 104 open into the lower chamber 52.
    As can be understood with the aid of Figures 8 and 9, the first end 72 of the tubular portion 70 of the tuba 18 is shaped to mate with the top connector 106 of the visor.
    Consequently, it is understood that the central duct 108, as well as the first and second lateral conduits 110, 112 open into the single air duct 90 of the tuba.
    Referring to FIG. 4, we will now describe how the flexible skirt 22 is fixed to the visor 20.
    As can be understood with the aid of FIGS. 1B, 2 and 4, the flexible skirt 22 has a peripheral edge 120 which surrounds a sealing lip 122.
    This sealing lip 122 is shaped to bear on the face of the user in order to prevent water from entering the mask.
    The peripheral edge 120 has a first lateral part 124 which, as can be understood with the aid of FIG. 4, covers the first exhaled air exhaust channel 102.
    The peripheral edge of the skirt has a first lateral part in which the first exhaust channel is engaged in order to prevent water from entering said first exhaust air channel.
    To do this, the first side part of the peripheral edge of the skirt 20 has an upper wall 126 and two side walls 128, 130. It is understood that the upper wall and the two side walls form a single piece with the skirt.
    The side walls 128 and 130 flank the two ribs 105, 107 of the first exhaled air exhaust channel while the upper wall covers the first exhaled air exhaust channel in order to ensure sealing.
    Preferably, one of the ribs has a longitudinal projecting portion which cooperates with one or the other of the side walls of the peripheral edge of the skirt in order to prevent the peripheral edge from remaining properly in place relative to the first channel. exhaust air exhaust.
    The peripheral edge of the flexible skirt 22 also includes a second lateral part 130 which covers the second exhaled air exhaust channel 104.
    According to the invention, the exhaled air exhaust device 100 includes a first non-return valve 140 which is arranged to allow a flow of exhaled air directed from the lower chamber 52 towards the air duct 90 of the tuba during a user expiration phase.
    It is therefore understood that, during an expiration phase, the flexible flap 58 of the partition 40 closes, while the first non-return valve 140 of the exhaled air exhaust device opens to let the exhaled air flow from the lower chamber 52 to the exhaled air exhaust device 100, and more particularly to the first exhaled air exhaust channel 102, then to the air duct 90 of the tuba and then to be evacuated via the slots 34.
    Furthermore, the first non-return valve 140 is closed during a user inspiration phase. Also, the user does not breathe the air contained in the snorkel or in the exhaled air exhaust device during an inspiration phase.
    As can be seen in FIGS. 5 and 6, the first non-return valve 140 is arranged in a lower end part 101 of the exhaled air exhaust device. More precisely, the first non-return valve 140 is arranged in a lower end portion 102a of the first exhaled air exhaust channel.
    In this example, the first non-return valve 140 is disposed between the lower chamber 50 and the exhaled air exhaust device 100. More specifically, the first non-return valve 140 is disposed between the lower chamber 52 and the first exhaled air exhaust channel 102.
    Without departing from the scope of the present invention, the first non-return valve 140 could be placed in the lower chamber 52.
    According to an advantageous aspect of the invention, the first non-return valve 140 comprises a flexible membrane 142 which, in this example, consists of a portion of the flexible skirt 22.
    The flexible membrane is in the form of a substantially rectangular portion which projects from an internal face of the upper wall 126.
    In Figure 6, there is illustrated in solid lines the first check valve in the closed position. It is also shown in dotted lines in the open position.
    The first non-return valve 140 also comprises a valve seat 144 arranged to cooperate with the flexible membrane 142, the valve seat 144 being integrated into the visor. In the closed position, the flexible membrane rests on the valve seat to close the openings.
    With the aid of FIGS. 3, 5 and 6, it can be seen that the first exhaled air exhaust channel 102 comprises, in this example, two openings 150 which open into the lower chamber 52.
    It can be seen that these two openings are formed in the internal rib 107 of the exhaled air exhaust device 100.
    The flexible membrane 142 is shaped to close the two openings 150 during a user inspiration phase.
    It is therefore understood that the flexible membrane 142 is situated inside the first exhaled air exhaust channel 102 opposite the two openings 150.
    As explained above, the exhaled air exhaust device 100 further includes the second exhaled air exhaust channel
    104.
    The exhaled air exhaust device 100 moreover comprises a second non-return valve 160, similar to the first non-return valve 140, which is arranged to allow a flow of exhaled air directed from the lower chamber 52 towards the conduit d air 90 of the snorkel during a user expiration phase.
    The second non-return valve 160 is closed during a user inspiration phase.
    In other words, the second non-return valve 160 functions like the first non-return valve 140.
    Still with reference to FIGS. 5 and 6, it can be seen that the visor further comprises a purge valve 180, which is formed in a lower end part of the visor 20.
    This purge valve 180 is partially covered by a protective plate 182, which in this example forms a single piece with the visor 20. This protective plate has the function of preventing damage to the purge valve 180.
    Referring again to FIGS. 7, 8 and 9, it can be seen that the mask has an unlocked locking system which is labiated from the snorkel to the body. This locking system comprises, in this example, a tongue 200 which extends from the first end 72 of the tubular portion 70.
    Furthermore, the tongue 200 is provided with a fixing portion
    202.
    The strapping 24 also comprises a top 24a in which an opening 204. The opening 204 is through.
    The fixing portion 202 of the tongue 200 is shaped to be received in the opening 204 in order to lock the snorkel to the body.
    With the aid of FIGS. 8 and 9, it is understood that the tongue is deformable so that when the tuba 18 is engaged with the body 12, the top connector 106 engages in the air channel 90 of the tuba 18 and the fixing portion 202 engages between the upper part of the hoop 24 and the top connector, until the fixing portion is engaged in the opening 204.
    It is therefore understood that when the snorkel is mounted to the body, at least part of the tongue is disposed below the strapping.
    In other words, the tongue engages from below the hoop. As can be seen in Figure 9, the tongue is engaged between the top connector 106 and the strapping.
    Furthermore, the fixing portion 202 also constitutes a push button arranged to allow a user to disengage the fixing portion from the opening so as to separate the snorkel from the body.
    To do this, the user presses on the fixing portion so as to deform the tongue while pulling on the tuba, in order to pass the fixing portion under the strapping. The fixing portion 202 consists of a bulge 206, which has a beveled shape which is shaped to come to engage in the opening when the tuba is mounted to the body.
    In this example, the bulge has an annular shape.
    Furthermore, the tongue 200 has a receiving portion 208 which is disposed between the fixing portion 202 and the tubular portion 70 of the tuba. The receiving portion is shaped to receive a portion 24b of the hoop 24 forming a stop when the snorkel is mounted to the body.
    Furthermore, the receiving portion 208 and the abutment portion of the hoop 24 are engaged together by form cooperation when the snorkel is mounted to the body, which has the effect of preventing an untimely unlocking of the snorkel.
    Furthermore, the receiving portion 208 comprises two ribs 210, 212 arranged on either side of said receiving portion 208, these ribs extending between the first end of the tubular portion and the fixing portion, and cooperating with two grooves 214, 216 visible in FIG. 10 - of the strapping when the snorkel is mounted to the body. The advantage is to ensure the stability of the snorkel when it is mounted on the body.
    Furthermore, the top connector 106 has a recess 220 which is located below the fixing portion when the snorkel is mounted to the body. This recess accommodates the deformed tongue during the engagement of the snorkel on the body. It also makes it possible to leave a space for the deformation of the tongue when the snorkel disengages from the body.
    Finally, it can be seen that the mask further comprises a seal 250 arranged between the body and the tuba. This seal
    250 is received in an annular groove 252 formed on the top connector of the visor.
    Referring to Figures 11 and 12, we will describe a mounting bracket for an accessory, for example a camera. This fixing support is preferably removable.
    The fixing support 300 has a mounting portion 302 proper which has a cylindrical fixing member 304, known moreover, for receiving a camera. This fixing support 300 is removably mounted to the body of the mask.
    The fixing support 300 also comprises two legs 306, 308 which end in two wings 310 which are shaped to cooperate with the strapping of the body in order to block the fixing support with respect to the body.
    The fixing support 300 also includes a connection portion 312 which extends between the tabs 306, 308 and the fixing member 304. This connection portion has the shape of a hook shaped to rest on the visor when the support is mounted. mask, whereby the wings and the connecting portion immobilize the fixing support relative to the body. In addition, the hook shape is arranged so that the fixing member 304 is located substantially at eye level of the user. Thanks to this advantageous positioning, the camera is necessarily submerged when the body of the mask is submerged, the snorkel being out of the water. It is therefore of interest to ensure that the camera films underwater and not the surface of the water.
    The diving mask also comprises a holding device 400, visible in FIGS. 1B, 2 and 7, which comprises a central attachment element 402 situated between two lateral attachment elements 404, 406.
    The central attachment element 402 is in the form of a mushroom, the head 403 of which is shaped to be successively introduced into a first hole 408 and then into a second hole 410 juxtaposed with the first hole, formed near the first end. of the tubular portion of the tuba. As can be seen in FIG. 7, the first hole 408 has a diameter greater than that of the second hole 410. The head 403 of the central attachment element 402 has a diameter less than that of the first hole but greater than that of the second hole. It is therefore understood that the central attachment element 402 is secured to the tuba when the head is brought into the second hole 410.
    As can be understood with the aid of FIGS. 1B and 2, the lateral attachment elements 404, 406 have the form of rods which are intended to be inserted in openings 412, 414 made in the frame, preferably in the strapping, in order to secure the holding device relative to the body.
    It is therefore understood that the holding device 400 has the function of holding the snorkel to the body, even when the tubular portion of the snorkel is fluidly decoupled from the top connector, which makes it possible to avoid losing the snorkel.
    The holding device 400 is preferably made of a flexible material of the rubber type.
