SUMMARY OF THE INVENTION The object of the invention is already achieved by a connection head for a filter candle according to claim 1. Advantageous embodiments and developments of the invention are the subject of the dependent claims, the description and the drawings. The invention relates to a connection head for a filter candle. In particular, the invention relates to a connection head for a filter candle, which is filled with a treatment material, in particular an ion exchange material, and which can be connected inline into a water pipe. [0010] The connection head comprises a housing with an inlet and an outlet. Inlet and outlet can be connected to a water pipe, especially a hose. According to the invention, the inlet and / or the outlet, preferably both inlet and outlet, has a connection to which a removable adapter piece for a water pipe can be attached. According to the invention, the connection piece of the inlet and / or the outlet, which is used to attach the water pipe, in particular the hose, is designed as a removable adapter piece from which the water pipe / 20 AT15 908U1 2018-08-15 Austrian Patent office can be connected. Here, the adapter piece in addition to the connection head-side connection has a connection for the water pipe, in particular a thread or a plug-in socket for a hose, or is inseparably connected to a water pipe, in particular a hose. It is thus possible in a simple manner to provide the connection head of the filter candle with different connection pieces. The adapter piece can be provided, for example, with different diameters or different threads or as an angled and non-angled version, so that the connection head of the filter cartridge can be easily adapted to the on-site connection conditions. The or the connections of the connection head for the adapter piece are preferably designed such that they are at least partially embedded in the housing. The connections preferably protrude less than 2 cm from the housing wall. A particularly compact design can be achieved in this way. In a preferred embodiment of the invention, the adapter piece can be attached by means of a quick-release fastener. A quick-release fastener is understood to mean that the adapter piece can be attached by the user without tools. In particular, a quick release fastener is provided, which comprises a locking element which locks the adapter piece by a rotation of less than 90 ° and preferably by a rotation of approximately 45 °. Already by pushing on the quick-release fastener, the adapter piece is preferably both mechanically fastened and connected to the connection in a liquid-tight manner. By locking a higher compression, which can withstand pressures of over 3 bar, is achieved. Thus, the adapter piece can be operated from a side in a cramped installation position in a simple manner. In a preferred embodiment of the invention, the locking element can be pushed onto the connection of the connection head. It is particularly provided that the adapter piece can first be placed on the connection in such a way that it is already stuck in such a way that it no longer falls off. This can be done, for example, by sliding it onto a tubular section of the connection. Then the locking element is preferably pushed on from the side and it is locked by a rotary movement of the adapter piece such that a pressure-tight, tight connection is now made. In an alternative embodiment of the invention, the locking element is designed such that it unlocks or locks the adapter piece by a sliding movement. In particular, the locking element can be designed as a displaceable sleeve. In a further development of the invention, the quick-release fastener is designed such that when the quick-release fastener is locked, the removable adapter piece is pressed onto the connection with an axial force. [0028] The tightness of the connection can thereby be improved. This can be achieved, for example, in that two corresponding sliding elements have an incline or that at least one sliding element has an inclined surface. 2/20 AT15 908U1 2018-08-15 Austrian Patent Office In a preferred embodiment of the invention, the locking element jams in a locked end position. It is further provided according to a preferred embodiment of the invention that the locking element is locked in a locked end position. In a further development of the invention, the removable adapter piece is secured against rotation with respect to the connection. In particular, it is provided that the adapter piece can be used in positions rotated by 90 ° or less, preferably in 30 °, and is secured against rotation in this position. In particular when using angular adapter pieces, it is possible in a simple manner to align the adapter piece in such a way that it is optimal for a connection provided by the customer. The anti-rotation is preferably carried out in a form-fitting manner. In contrast to an anti-twist device, for example by clamping, a twist-proof connection is provided, which does not yield even with larger forces, which can occur, for example, when installing a hose. The adapter piece preferably has a connection piece for a water pipe. The connector is designed in particular as a thread or as a plug-in socket for a hose. In a further embodiment of the invention, the adapter piece is inseparably connected to a water pipe designed as a hose. In particular, a hose is clamped onto the adapter piece, for example with a clamping sleeve. In particular, this can be an armored hose. It is therefore not necessary to provide a hose, in particular an armored hose, with a union nut, which enables a cheaper and more compact design of the connection. In one embodiment of the invention, the connection head comprises an actuating member for an adjustable bypass. The adjustable bypass is part of a blending device, via which the proportion of the incoming water that runs over an ion exchanger can be adjusted. In this way, the filter candle can be easily adjusted depending on the degree of hardness of the water, the on-site water connection and the desired hardness. The housing has receptacles for a wall bracket in a preferred embodiment of the invention. It is particularly provided that the housing can be used in a claw-shaped or fork-shaped wall holder. The invention further relates to a set with a connection head described above and at least two different adapter pieces. In particular, the adapter pieces have a different connection for a hose, for example push-in nozzles in different diameters, threads in different diameters or are angled and not angled. [0044] The invention further relates to a filter candle which is provided with the connection head described above. BRIEF DESCRIPTION OF THE DRAWINGS The subject matter of the invention will be explained in more detail below with reference to an exemplary embodiment with reference to the drawings in FIGS. 1 to 18. 3.20 AT15 908U1 2018-08-15 Austrian Patent Office Fig. 1 is a perspective view of a connection head according to the invention.

DETAILED DESCRIPTION OF THE DRAWINGS Fig. 1 is a perspective view of an embodiment of a connector head 1 of a filter cartridge. The connection head 1 is connected to a housing of the filter candle, not shown here, which is filled with an ion exchange material. The connection head 1 comprises a housing 2 with an inlet and the outlet 3 to be seen here. The outlet 3 comprises a connection 5 for an adapter piece 6. The adapter piece 6 comprises a hose connection 7. The connection 5 of the outlet 3 has an annular collar 8. Between the collar 8 and the tubular piece of the connector 5, an annular groove 39 is provided, into which the adapter piece 6 can be inserted. [0066] A locking element 9 is also shown. 1, adapter piece 6 and locking element 9 are still separated from the rest of the connection head 1. Inlet and outlet 3 are preferably located on opposite side walls of the connection head 1. In this embodiment, the connection head 1 further comprises an actuation 4/20 AT15 908U1 2018-08-15 Austrian Patent office organ 10 for a bypass. The bypass can be used to set how much of the incoming fresh water is passed through the ion exchanger. The degree of hardness of the treated water can be adjusted in this way. In the area of the actuator 10, the connection head 1 comprises a window 11, through which the setting position of the actuator 10 for the bypass can be read. The connection head 1 further comprises receptacles 12 for a wall bracket 13 below the inlet and outlet. The wall holder 13 is essentially U-shaped and comprises claw-like extensions in which the receptacles 12 can be inserted. [0073] First of all, the wall holder 13 can be mounted on the wall. The filter candle with the connection head 1 can then be inserted into the wall holder 13. With reference to the perspective representations according to FIGS. 2 to 4, it will be explained how the adapter piece 6 is mounted on the connection head 1. As shown in FIG. 2, in a first step the adapter piece 6 is inserted into the connection 5, specifically the annular groove 39 shown in FIG. 1. The adapter piece 6 is now already secured against falling out on the connection head 1. Then, as shown in FIG. 3, the locking element 9 is pushed on. In this embodiment, the locking element is first pushed from the side and then, as shown in FIG. 4, locked by a rotary movement, preferably by a rotary movement of 90 ° or less, in particular 45 °. The adapter piece 6 is now firmly and pressure-tightly connected to the rest of the connection head 1. Using the locking element 9, which forms a quick-release fastener, the adapter piece 6 can be exchanged for other adapter pieces in a very simple manner in order to adapt the connection head 1 to different on-site connection conditions. Fig. 5 is a detailed view of the connector 5 for the adapter piece. It can be seen that the connection 5 has positive locking elements 14. In this exemplary embodiment, the form-locking elements 14 are designed as projections that are arc-shaped in cross section. Twelve protrusions are distributed over the circumference of the connector. The corresponding adapter piece can be attached in a twist-proof manner in twelve different positions, each rotated by 30 °. This is particularly advantageous in the case of angular adapter pieces. For example, the hose connection can easily be aligned upwards, downwards or to one of the sides. Fig. 6 is a perspective view of the locking member 9. The locking element 9 is substantially U-shaped in order to be able to be pushed onto the connection 5 from the side. Thus, the locking element 9 has a recess 15, which is open to one side, whereby the direction of postponement is defined. Fig. 7 is a perspective view of the locking element 9, wherein the 5/20 AT15 908U1 2018-08-15 Austrian Patent Office Underside of the locking element 9 is shown. Two collars 16, 17 spaced apart from one another can be seen. The collars 16 and 17 extend around the recess 15, the recess 15 being larger in the region of the collar 16 than in the region of the collar 17. The collar 16 serves for the rotatable connection of the locking element 9 with a connection 5 of the connection head. For this purpose, the locking element 9 with the collar 16 is pushed under the collar 8 shown in FIG. 1 of the connection 5. The collar 17, on the other hand, engages in a corresponding groove in the adapter piece (36 in FIG. 11) and thus fixes the adapter piece in the axial direction. On the open side of the recess 8, the collars 16 and 17 each include a bevel 18, 19 in order to be able to put the locking element 9 more easily. The collar 17 also has a thickened region 20 on the open side. Because of this thickened area, the locking element 9 is already secured after falling through the corresponding groove (36 in Fig. 11) together with a molded seal (40 in Fig. 20) of the adapter piece against falling out. 8 is a plan view of the front of the locking element 9. It can be seen that the recess 15 tapers in the region of the open side and thus forms a passage 21 which is smaller than the diameter of a segment of the recess 15 in the form of a circular segment behind it. The passage 21 opposite the wing of the locking element 9 act as a clamping element and also secure the locking element 9 against falling out when it has been pushed from the side. Fig. 9 is a plan view of the underside of the locking element 9. Below the collar 16, the locking element comprises on its sides two opposite webs 22, 23. The webs 22, 23 point in the direction of the center of the recess 15. At their ends, the webs 22, 23 have two lugs 24, 25, which are preferably rounded. Fig. 10 is a sectional view taken along the line D-D of Fig. 9. The web 23 is thicker than the web 24. Accordingly, the distance between the collar 16 and the collar 17 decreases in the direction of the web 23. The groove formed between the collars 16, 17 thus narrows over their circumference. As a result, in cooperation with the collar 8 shown in FIG. 1, the thickness of which changes over the circumference, jamming is achieved in a locking position, which will be explained in detail below with reference to FIG. 15. Between the collar 8 and the locking element 9 so inclined sliding surfaces are formed. FIG. 11 is a perspective view of the adapter piece 6 already shown in FIG. 1. The adapter piece 6 is formed in this embodiment as an angle piece. On the connection side to the connection head, the adapter piece 6 comprises an annular groove 36 into which the collar 17 shown in FIG. 7 engages. Furthermore, the adapter piece comprises a hose connection 7, which is designed as a thread in this embodiment. On the side of the connection to the connection head, the adapter piece Form6 / 20 AT15 908U1 2018-08-15 Austrian Patent Office Closing elements 26, which in this embodiment are designed as rounded recesses and which are complementary to the form-fitting elements 14 of the connection 5 shown in FIG. 5. In another embodiment, not shown here, the adapter piece has no positive locking elements. An adapter piece designed in this way can also be rotated through 360 ° in the locked state and, if necessary, can be brought into any position. Fig. 12 is a sectional view of the adapter piece shown in Fig. 11. The connection on the connection head side comprises an inner tube 27. At the end of the tube 27, an annular groove 28 extends around the outside of the tube, which is used to insert a molded seal that is not used in this illustration (40 in FIG. 20). Fig. 13 is a perspective view of the connection head 1, with the outer housing removed and the view of the housing inner part 29 is released. The connection head 11 has an inlet 4 and an outlet 3, wherein inlet 4 and outlet 3 are essentially identical and each have a connection 5 with a collar 8 for fitting a locking element. 14 is a top view of the top of the connection head 6 shown in FIG. 13 with the inlet 4 and the outlet 3. Fig. 15 is a sectional view of the connection head 1 along the line A-A shown in Fig. 14. Inlet 4 and outlet 3 are also shown here, which are opposite one another. The configuration of one of the connections 5 will now be explained with reference to the inlet 4. The connection 5 has a tubular section which ends with the end face 30 and which is pushed into the adapter piece when the adapter piece is installed. The connection 5 comprises a collar 8, which serves the connection to the locking element, which in turn has the collar 16 shown in FIGS. 9 and 10 with the webs 22 and 23. The collar 8 is formed on the top 31 in this embodiment thicker than on the bottom 32. The thickness of the collar 8 thus changes over its circumference. In cooperation with the geometry of the locking element shown in Fig. 10 with a groove between the collars 16 and 17, which narrows over the circumference, on the one hand, a force can be generated in the axial direction with which the adapter piece on port 5 is pressed. At the same time, the locking piece after placing on the collar 8 first play, but then jams in a locked position. Fig. 16 is a sectional view taken along the line B-B shown in Fig. 14. This section now runs along a plane below the collar of the connector 5. The connection 5 with the positive locking elements 14 for the adapter piece can be seen. It can also be seen that a tubular section 33, which serves as a carrier for the collar 8, extends around the connection 5 with the interlocking elements 14. Fig. 17 is a detailed view of area C of Fig. 16. In this detailed view it can be seen that two opposite projections 34 protrude from the tubular section 33. 7.20 AT15 908U1 2018-08-15 Austrian Patent Office The projections 34 are preferably rounded and serve to lock the locking element 9 in a locked position. If the locking element 9 is moved into the locked position shown in FIG. 4, the lugs 24, 25 shown in FIG. 9 slide over the projections 34. In the locked state, the webs 22, 23 shown in FIG. 9 come to rest on the stops 35, so that the locking element is locked in the locked state, since the webs 22, 23 lie between the projections 34 and the stops 35 , To remove the locking element, the user must first apply an increased force until the lugs 24 have slid over the projections 34. 18 is an illustration of an adapter piece 6, which is also designed as an angular adapter piece. In contrast to the exemplary embodiment shown above, the adapter piece is inseparably connected to a hose 38. For this purpose, the hose 38 is pressed onto the adapter piece 6 by means of a clamping sleeve 37. In this way, an inexpensive and compact connection option is provided which is flexible and by means of which filter candles can be adapted in a very simple manner to different on-site connection conditions. 19 is a further detailed view of the connection head with the adapter piece 6 inserted. As shown in the detailed view of the connection area B according to FIG. 20, a molded seal 40 is now pressed into the groove (28 in FIG. 12) of the adapter piece 6. The molded seal 40 is firmly connected to the rest of the adapter piece 6. The user therefore does not need to insert a seal and the seal cannot be lost. The seal between the adapter piece 6 and the connection 5 takes place via the molded seal 40. The connection is preferably already liquid-tight after plugging the adapter piece 6 and is pressed again by the locking means by the locking element in order to withstand even higher pressures, such as they are on site. 8/20 AT15 908U1 2018-08-15 Austrian Patent Office LIST OF REFERENCE NUMBERS connection head casing procedure Intake connection adapter piece hose connection collar locking element Bypass actuator window admission wall mount Form-fitting element recess collar collar bevel Bevel thickened area passage web web nose nose Form-fitting element tube groove Housing inner part front top Underside of tubular section head Start attack groove collet tube groove shaped seal 9.20 AT15 908U1 2018-08-15 Austrian Patent Office
