    The invention relates to a plug-in device which is arranged in an end region of a line, in particular of a tube or hose, and which comprises a plug-in sleeve arranged on an outer side of the line, which can be inserted into a corresponding receiving sleeve. In the inserted state, one or more radial projections on an outer side of the plug-in sleeve engage in grooves on an inner side of the receiving sleeve. Furthermore, a method for producing such a plug-in device is specified.
    From the prior art, for example from EP 0 743 479 B1, plug devices are known in which a one-piece plug-in sleeve made of metal or sheet metal is placed on the end of a tube. These sockets are manufactured based on suitable metal forming techniques such as deep drawing. For the formation of radial projections on the outer side of the plug-in sleeve, which secure the plug-in device against rotation in the receiving sleeve, further complex processing steps such as cutting, punching and bending are necessary, whereby the manufacturing cost is increased. In addition, the use of these forming and machining processes in the production of plug-in metal housings for cables with relatively small outer diameters of less than 2.5 cm is very problematic and the production of such receptacles in this way is at least with considerable effort or with considerable Problems connected, if not impossible. The smaller the dimensions of the plug-in sleeve, the more difficult it is, in particular, to manufacture the anti-twist device from the metal sheet. For very small outer diameters especially less than 1.5 cm and thus very small sockets the production of anti-rotation by means of the previously described metalworking process is even virtually impossible. Another • · • *
    Disadvantage of one-piece sockets of metal is that the possibilities of shaping during manufacture are limited to a certain extent and thus can not be implemented in every application, a receptacle or plug-in device with the best possible geometry.
    The present invention is therefore based on the object to provide a plug-in device in an end region of a pipe, in particular a pipe or hose, which can be made simpler and less expensive and is also suitable for small outer diameters preferably less than 1.5 cm. In particular, the receptacle or parts thereof should also have an improved or optimal geometry. Moreover, it is an object of the invention to provide a method for producing a plug-in device in an end region of a pipe, in particular a pipe or hose, which is easier and less expensive to carry out and also suitable for small outer diameters of preferably less than 1.5 cm ,
    The object of the invention is achieved with a plug-in device of the type mentioned, in which moreover the receptacle viewed in the longitudinal direction next to one end of the line comprises a front part made of metal and then a rear part of a plastic material which is more elastic with respect to the material of the front part. Furthermore, one or more radial projections are arranged on the outside of the plug-in sleeve on the plastic rear part, which can be inserted or inserted into the frontally open grooves on the inside of the receiving sleeve.
    Due to the at least two-part design of the receptacle made of a metallic front part and a material of the front part elastic rear part made of a plastic plug-in device is easier and less expensive manufacturable, especially because the rotation on the rear part, which by the at least one radial projection, preferably by two diametrically formed on the outside of the rear part opposite radial projections can be made in a very simple manner, for example in an injection molding process. Furthermore, the use of an injection molding process creates the possibility of the geometry of the rear part of the plug-in sleeve and in particular the radial one To improve or optimize projections of the anti-rotation device,
    If a line with an outer diameter of less than 2.5 cm, preferably less than 1.5 cm are provided with a plug-in device, so the production of the necessary, small receptacle in a relatively simple manner by the just described, two-part Construction possible. A one-piece production of such a small plug of metal, for example by means of a thermoforming or forming process is associated with at least a considerable effort or with considerable problems, if not impossible.
    With such small dimensions, in particular the production of the anti-twist device from a metal sheet is very difficult or virtually impossible.
    It is particularly advantageous to design the plug-and-socket device in such a way that a front section of the rear part is sealingly arranged between the outside of the line and a rear section of the front part in an overlapping area of the plug-in sleeve and that pressing from the inside into the line in the overlapping area of the front part and the back part is trained. By the sealing, i. positive and non-positive arrangement of the front portion of the rear part between the outside of the line and a rear portion of the front part is ensured in conjunction with the elasticity of the rear part a sufficient and reliable seal in the overlapping region and thus between the line and the socket. In connection with the pressing therefore no complicated and thus vulnerable processes such as gluing, soldering or welding are required for fixing and sealing of the receptacle in the end region of the line.
    In addition, such a plug-in device is also easier and less expensive manufacturable, since the positioning or attachment of the seal is simplified as a part of the rear part between the line and socket. In particular, there are no time-consuming and error-prone processes such as the 4 4 4 "t 4 - * *

    Insertion of a separate sealing ring made of an elastomer or a bonding process for fixing a sealing element necessary. It is expedient if the projection or projections of the anti-rotation lock on the rear part of the plug-in sleeve each have an end face extending at right angles to the longitudinal direction of the plug-in sleeve on the end face facing the grooves. As a result, an at least partial insertion or insertion of the plug-in sleeve in the receiving sleeve is made impossible in the case of projections and grooves which are not aligned with one another, as is possible in particular with projections having obliquely extending end faces. As a result, in particular damage to the receptacle and the receiving sleeve can be effectively avoided.
    Such a rectangular design of the end face of each projection is also made possible only by the production of the rotation on the rear part of the receptacle by means of an injection molding. In the known from the prior art production of anti-rotation of a metal sheet by forming in principle, only projections with oblique front end faces are possible especially for small pipe diameters or plugs.
    It is also particularly favorable if at least one of the projections projects forwards towards the front end of the plug-in sleeve over a tangential groove in the outer side of the plug-in sleeve, into which groove, in particular a clamp of the receiving sleeve for detachable connection of the plug-in sleeve in the receiving sleeve, a projection having. In this way, an incorrect or twisted insertion of the receptacle in the receiving sleeve by at least one such projection prevents the rotation during a plugging as early as possible.
    It is also advantageous if the one or more protrusions of the rotation are made massive and at a line outer diameter of about 1.5 cm each have a side surface of the projections has an area of more than 2.5 mm2, preferably of more than 5 mm2. This results in the advantage of low surface pressure forces on the outer side surfaces of the projections or the corresponding, inner side surfaces of the grooves, provided that the corresponding groove side surfaces are correspondingly large in area and opposite to the side surfaces of the projections. As a result, damage or increased wear of the side surfaces of the projections as well as the corresponding grooves are avoided. It is favorable if the rear part of the plug-in sleeve is formed from a polyamide (PA), in particular from PA 6.12, or a thermoplastic elastomer (TPE). Basically, the material of the rear part should have a tensile modulus of about 100-300 MPa. Such a choice of material represents an ideal compromise between the stability of the rear part and the tightness of the plug-in device between the line and the socket.
    It is also particularly advantageous if the front part and the rear part of the plug-in sleeve can be connected via a latching device. In this way, the parts of the receptacle are easy and sufficiently secure connectable and hold even before mounting the receptacle on the line already together. This represents in particular an advantage over a plug-in sleeve made of two metal parts, since relatively complicated processes such as press-fitting and gluing would be required for the effective connection of two such metal parts, because the production of a latching or coupling device is complicated and difficult or especially in the case of two metal parts small sockets would be impossible.
    It is also advantageous if a small air gap is formed between the outside of the line and an inner side of the receptacle in the unfinished state of the receptacle on the line, which is sealed after fixing the receptacle on the line at least one point. Such an air gap is preferably less than 0.5 mm, in particular less than 0.1 mm wide and simplifies the manufacture of the plug-in device, since the plug-in sleeve can be easily positioned in the end region on the line and then fixed.
    The object of the invention is further achieved by a method for producing a plug-and-socket device in an end region of a pipe, in particular of a pipe or hose, with a pipe arranged on an outside of the pipe
    Plug-in sleeve which can be inserted into a corresponding receiving sleeve and wherein in the inserted state, one or more radial projections on an outer side of the plug-in sleeve in grooves on an inner side of the receiving sleeve eingrei fen solved in which the following measures are performed. It is a front part made of a metal in particular by deep drawing or forming and a rear part made of a material more elastic than the material of the front part, in particular by injection molding, wherein the one or more radial projections are formed on the outside of the socket on the rear part and the or the projections in the frontally open grooves on the inside of the receiving sleeve can be inserted or inserted. Then, the front part and the rear part are assembled to form the one-piece plug-in sleeve and the plug-in sleeve thus formed is pushed into the end region of the conduit, wherein the front part of the plug-in sleeve is positioned next to one end of the conduit. In a further step, a compression from the inside is applied to the line in an overlap region of the front part and rear part, in which overlapping region of the plug-in sleeve, a front portion of the rear part between the outside of the conduit and a rear portion of the front part is sealingly arranged.
    The technical effects or advantages achieved by the method just described for producing a plug-and-socket device can be taken from the preceding description parts. In particular, the advantage should be mentioned here that in such a method, a check whether a sealing element such as a sealing ring made of an elastomer between line and socket at all present or properly positioned is basically eliminated, since no separate sealing element is used the density member is formed by the front portion of the elastic rear part, which portion is sealingly disposed in the overlapping area of the front part and the rear part between the outside of the conduit and the rear part of the front part.
