Alternatively or additionally, it can be provided that the free cut is designed to be limited in the circumferential direction. This creates a simple way of supporting the at least one spring element at its ends. In an advantageous embodiment, it can be provided that a plurality of spring elements are arranged in the circumferential direction, which spring elements touch each other in pairs at their ends. This makes it possible to create a structure with increased rigidity, which can increase the holding force on the locking projections. In this case, it can be provided that the spring elements are each supported at their ends. This increases the spring force of the spring elements.In an advantageous embodiment, it can be provided that a sequence of spring elements is interrupted in a circumferential section containing the hose connection. Thus, an injection molding tool for producing the sanitary outlet piece can be designed more simply by dispensing with the formation of free cutouts in a shadow of the hose connection.

In particular, to achieve the stated object, in a sanitary outlet piece of the type described above, the invention proposes that the locking projection be designed at a distance from a free boundary of the at least one spring element. Thus, a part of the spring element can be used as an insertion stop, independent of a locking function.In an advantageous embodiment, it can be provided that the locking projection is formed in an axial section on an axially rectilinear section of the at least one spring element. This allows a rectilinear transmission of a force applied to the spring element to a fastening location of the spring element. This means that even large forces can be absorbed at the insertion stop. Alternatively or additionally, to achieve the stated object, the invention proposes a sanitary outlet piece according to the third independent claim. In particular, to achieve the stated object, the invention proposes in a sanitary outlet piece of the type described above that reinforcing ribs are formed on the outside of a base delimiting the jet regulator receptacle. This makes it possible to support a material region subjected to strong internal pressure.In an advantageous embodiment, it can be provided that the reinforcing ribs each extend into a side wall of the jet regulator receptacle. Thus, a mechanical connection between a base and a PC 231110 C 5 / 24 October 11, 2023 side wall of the jet regulator receptacle can be reinforced. In an advantageous embodiment, it can be provided that at least one reinforcing rib of the reinforcing ribs is arranged in a forward extension of the hose connection. Thus, a compact design of the outlet piece can be achieved. Alternatively or additionally, to achieve the stated object, the invention proposes a sanitary outlet piece according to the fourth independent claim. In particular, to achieve the stated object, in a sanitary outlet piece of the type described above, the invention proposes that a preferably latching holding means be formed on a rear side facing away from an outlet side.Particularly advantageously, the jet regulator housing is therefore not fastened via the outer circumference. In an advantageous embodiment, it can be provided that the holding means is designed as a preferably centrally arranged pin. This results, for example, in the possibility of generating an easy-to-implement, detachable and nevertheless effective pin connection. In an advantageous embodiment, it can be provided that the holding means holds positively and / or non-positively on the rear side facing away from the outlet side.

Alternatively or additionally, to achieve the stated object, the invention proposes a sanitary outlet piece according to the fifth independent claim. In particular, to achieve the stated object, in a sanitary outlet piece of the type described above, the invention proposes that a curvature along a shortest path between an inner end of the fastening region and a rearmost location of the aerator receptacle has a uniform sign. This avoids notches due to excessive curvatures that can occur due to changes in the sign of the curvature. This can help to increase the stability of the aerator receptacle under pressure.Alternatively or additionally, to achieve the stated object, the invention proposes a sanitary outlet piece according to the fifth independent claim. In particular, to achieve the stated object, the invention proposes in a sanitary outlet piece of the type described above that a circumferential section of an inner groove of the aerator receptacle is arranged in a forward extension of the hose connection. This makes it possible to achieve a low attachment of the hose connection to a base of the aerator receptacle. In an advantageous embodiment, it can be provided that an opening of the hose connection into the aerator receptacle is located eccentrically to an outlet opening of the aerator receptacle. PC 231110 C 7 / 24 October 11, 2023 aerator receptacle. Thus, the overall height of the outlet piece can be reduced by designing the aerator receptacle at a distance from a highest point of the aerator receptacle.In an advantageous embodiment, it can be provided that the outlet piece is formed in one piece, for example using an additive manufacturing process or as an injection-molded part. This simplifies assembly and reduces defects that could arise at interfaces. In an advantageous embodiment, it can be provided that the hose connection is designed to completely enclose a hose and / or to insert a hose, for example the one already mentioned, in the flow direction. This enables simple connection of the outlet piece to a hose. A preferred application can provide a sanitary fitting with a receptacle, preferably formed on an outlet pipe, in which a sanitary outlet piece according to the invention, for example as described above or claimed below, is arranged.In this case, it can be provided that at least one spring element, for example the at least one already mentioned, defines an insertion stop for the outlet piece. This provides a simple means for positioning the outlet piece in the position of use. In an advantageous embodiment, it can be provided that a groove for the at least one locking projection is formed in the receptacle, wherein the groove is open at its ends PC 231110 C 8 / 24 October 11, 2023 due to a material recess in the outlet pipe. This makes it possible to reduce the overall height of an outlet pipe because no material needs to be left over to form the groove in the outlet pipe on one side, where, for example, the outlet piece is at its lowest point due to an inclined position.It has been found that the remaining locking projections still develop sufficient holding force, particularly since the outlet piece is not subjected to the operating pressure of the water at the locking projections. In this case, the material recess and / or the open-ended design of the groove can be designed to correspond to an interruption in, for example, the aforementioned sequence of spring elements on the sanitary outlet piece. This allows for greater design and / or construction freedom below the hose connection. This can be used, for example, to simplify an injection molding tool.The invention enables the use of a spring element of a sanitary outlet piece according to the invention, in particular as described above and / or as claimed below, as an insertion stop when inserting the sanitary outlet piece, in particular into a receptacle of a sanitary fitting according to the invention, for example as described above and / or claimed below. This allows for simple assembly. The invention will now be described in more detail using exemplary embodiments, but is not limited to the exemplary embodiments. Further exemplary embodiments arise from combining the features of one or more claims with one another and / or with one or more features of the exemplary embodiment.

Fig. 5 shows a detailed view of an outlet piece according to the invention with a snap ring, Fig. 6 shows a detailed view of an outlet piece according to the invention with a spring element and aperture, Fig. 7 shows a detailed view of an outlet piece according to the invention from Fig. 2 with a hose connection at the top, Fig. 8 shows a detailed view of an outlet piece according to the invention with a bending element, Fig. 9 shows a detailed view of an outlet piece according to the invention with a spreading element, Fig. 10 shows a detailed view of an outlet piece according to the invention with a holding means, and Fig. 11 shows a three-dimensional oblique view of another outlet piece according to the invention. Figs. 1 to 4 are described together below. PC 231110 C 10 / 24 11.October 2023 A sanitary fitting 1 has a base 2 for mounting on a support, for example, a washbasin. The base 2 supports a valve 3, for example, a single-lever mixer tap. The valve 3 controls a water flow to a water outlet 4, which is formed at a free end 5 of the outlet pipe 6. A hose 7 is guided in the outlet pipe 6, which is fluidically connected to the valve 3 on the one hand and to a sanitary outlet piece 8 on the other. The hose 7 ensures that water at the sanitary fitting 1 does not come into contact with the outlet pipe 6. The sanitary outlet piece 8 has a jet regulator receptacle 9, into which a jet regulator 10, which is designed as a cartridge and thus holds together even when uninstalled, can be inserted, screwed in here, and secured. The jet regulator 10 and thus the sanitary outlet piece 8 are arranged in a typical inclined position in the outlet pipe 6.The outlet piece 8 further has a hose connection 11, which is fluidically connected to the aerator receptacle 9, so that water can flow from the hose connection 11 to the aerator receptacle 9. The hose connection 11 is designed to completely enclose the hose 7 and to insert the hose 7 in the flow direction. Fig. 4 shows the sanitary outlet piece 8 in the removed state. PC 231110 C 11 / 24 October 11, 2023 On its outer circumference 12, the sanitary outlet piece 8 carries five spring elements 13, each of which has a locking projection 14 formed on it. The aerator receptacle 9 has a fastening area 15 in the form of an internal thread, which enables detachable fastening of the inserted aerator 10. In order to enable the locking projections 14 on the spring elements 13 to spring in the radial direction of the jet regulator, a free cut 16 is formed on each spring element 13, which defines the spring element 13.The cutout 16 is closed towards the outlet side 17 of the jet regulator holder 9. This allows the formation of an outwardly closed end face 18 which is easy to clean and offers few surfaces for dirt to accumulate. In a further exemplary embodiment (not shown), the cutout 16 is covered towards the outlet side 17 of the jet regulator holder 9. Each spring element is fastened at its two ends 20 oriented in the circumferential direction 19 of the outlet piece 8 via a web 21 to the side wall 22 of the jet regulator holder 9. Each cutout 16 is limited radially and in the circumferential direction 19. The chain of spring elements 13 thus forms a circumferentially closed outer contour at the height of the spring elements 13. The locking projections 14 must deform this chain or this ring PC 231110 C 12 / 24 October 11, 2023 in order to be able to spring.The spring elements 13 are arranged one behind the other in the circumferential direction 19 and touch each other at their ends 20, where they are supported by the webs 21. In a circumferential section 23 containing the hose connection 11, the sequence of spring elements 13 is interrupted, so that no spring element 13 is formed in the shadow of the hose connection and thus no free cut 16 needs to be formed, the tool of which would collide with a tool for forming the hose connection 11. Fig. 4 shows that the locking projection 14 is spaced from a free boundary 24 of the respective spring element 13. Fig. 2 shows that the free boundary 24 is used as an insertion stop without the function of the locking projection 14 being impaired.The locking projection 14 is thus formed in an axial section on an axially rectilinear portion 25 of the at least one spring element 13, so that a force from the insertion stop is transmitted in a straight line to the fastening location 26 of the spring element 13. Reinforcing ribs 28 are formed on the outside of a base 27 defining the jet regulator receptacle 8 in order to support a material area subject to significant internal pressure. The reinforcing ribs 28 extend into the side wall 22 of the jet regulator receptacle 8. At least one reinforcing rib 39 of the reinforcing ribs 28 is arranged in a forward extension of the hose connection 11 (see Figs. 2 and 4). PC 231110 C 13 / 24 11.October 2023 A curvature along a shortest path between an inner end 30 of the fastening area 15 and a rearmost location 31 of the jet regulator receptacle has a uniform sign, so that no changes in direction occur in the course of the path that could result in excessive curvatures and thus form notches in the material. There is a risk that such notches could lead to the bursting of the outlet piece 8 if pressure is applied via the hose connection. A circumferential inner groove 32 is formed on the base 27 of the jet regulator receptacle 9. The inner groove 32 defines the transition to the side wall 22. A circumferential section of the inner groove 32 (sectioned in Fig. 2 and arranged below the reinforcing rib 39) is arranged in a forward extension of the hose connection 11. In Fig.2 further shows that an opening 33 of the hose connector 11 into the jet regulator receptacle 9 is eccentric to an outlet opening 34 of the jet regulator receptacle 9. Thus, the overall height of the outlet piece can be reduced by forming the jet regulator receptacle 9 at a distance from a highest point 35 of the jet regulator receptacle 9 (to which the rearmost location 31 corresponds on the inside). It can be seen that the sanitary outlet piece 8 is formed in one piece, for example, using an additive manufacturing process or as an injection-molded part. The sanitary outlet piece 8 is formed in a receptacle 36 of the outlet pipe 6. The spring elements 13 with their common free limitation 24 define an insertion stop for the sanitary outlet piece 8. A groove 37 for the locking projections 14 is formed in the receptacle 36 - Fig.3 shows that the groove 37 is open at its ends 38 due to a material recess in the outlet pipe 6. Thus, on the side where the outlet piece 9 is at its lowest due to an inclined position, no material is required to form the groove 37 in the outlet pipe 6. The open end design of the groove 37 corresponds to an interruption in the sequence of spring elements 13 in the circumferential section 23. In contrast to Fig. 2, Fig. 5 shows a further embodiment of the sanitary outlet piece 8 according to the invention. The jet regulator holder 9 is fastened to the sanitary fitting 1 (Fig. 1) with an additional snap ring 48. In this embodiment, the snap ring 48 is designed as a separate element, but in an embodiment not shown in detail, it can be formed directly on the jet regulator holder 9. In contrast to Fig. 6 shows5 shows the sanitary outlet piece 8 with a spring element 13 open toward the outlet side 17. Also shown is a circumferential cover 40, which forms an annular surface, covers the cutout 16, and serves as an insertion stop. The cover 40 is free-standing on the outside. It can thus be said that the spring element 13 is oriented with its free end 45 toward the outlet side 17, and that the cutout 16 is covered by a circumferential cover toward the outlet side 17. In an embodiment not shown in detail, a spacer projection 41 is formed on the cover 40. In a further embodiment not shown, the aperture 40 has a turning aid 42. In contrast to the embodiment according to Fig. 2, Fig. 7 shows that the hose connection 11 is formed at the highest point 35 of the jet regulator holder 9. In contrast to Fig. 8,2, 5 and 6, that the spring element 13 has a bending element 46 in the form of a bending hook 49. The bending element 46, in this case the bending hook 49, is pushed into the groove 37 while the jet regulator 10 is being screwed in and thus fastens the jet regulator 10 to the sanitary fitting 1. Fig. 9 shows, in contrast to the previous embodiment from Fig. 8, that the spring element 13 has a spreading element 47 which interacts with the groove 37 provided for the spreading element 47. Fig. 10 shows an embodiment of a further sanitary connection piece 8 according to the invention with a locking holding means 43 formed on a rear side facing away from the mouth side 17. The holding means is designed in this embodiment as a centrally arranged pin 44. The holding means 43 enables a force-fitting and form-fitting connection with the sanitary fitting 1 (Fig. 1) and thus with the rear side facing away from the mouth side 17.In a further exemplary embodiment (not shown), the holding means 43 is held in a materially bonded and / or magnetic manner on the rear side facing away from the mouth side 17. PC 231110 C 16 / 24 October 11, 2023 Fig. 11 shows a further exemplary embodiment according to the invention. The same reference numerals are used for components and functional units that are functionally and / or structurally similar or identical to the preceding exemplary embodiments. The comments on Figures 1 to 10 therefore apply accordingly to Fig. 11. The exemplary embodiment according to Fig. 11 differs from the preceding exemplary embodiments in that the spring element 13 is axially aligned, so that the cutout 16 opens towards the mouth side 17 and the free end 45 points towards the mouth side 17. The cutout 16 is covered by a cover 40 towards the mouth side 17, whereby the free end 45 can continue to swing freely.A locking projection 14 formed by the free end 45 engages in a corresponding locking recess on a sanitary fitting. Spacer projections 50, preferably made of sacrificial material, are formed at regular intervals around the periphery of the aperture 40 to compensate for tolerances on the sanitary fitting. Thus, a sanitary connector 8 is proposed, which is designed for a fluidic connection of a jet regulator 10 to a hose 7 and for a mechanical fastening in an outlet pipe 6 of a sanitary fitting 1.
