DETAILED DESCRIPTION

(5) A tube holder 10 for a wiper arm 12 is shown in FIG. 1. The tube holder 10 comprises a bracket 14, a positively locking closure 16 and a tube receptacle 18. In addition, the tube holder 10 comprises a wiper receptacle 20. The bracket is designed to be folded onto the wiper receptacle 20. That means that the bracket 14 can be folded down such that said bracket comes to rest on the wiper receptacle 20 and closes the same off. A tube holder is shown in FIG. 1, the bracket 14 of which is not closed. The bracket 14 is fixed on the wiper receptacle 20 by the closure 16. Such a closed bracket 14, which is fixed by the closure 16, is shown in FIG. 2. In FIG. 2, the bracket 14 is folded down. In this position, the bracket 14 rests on the wiper receptacle 20.

(6) The wiper receptacle 20 is configured as a cavity 200 between the bracket 14 and the tube receptacle 18. This can be seen in FIG. 2. The closed bracket 14, which is folded onto the wiper receptacle 20, is disposed opposite the tube receptacle 18. The tube receptacle 18 points away from the wiper receptacle 20 respectively the cavity 200. Thus, the tube receptacle 10 has a closed cavity 200. A base 21 of the wiper receptacle and the bracket 14 are separated by the cavity 200. The bracket 14 as well as the base 21 have straight sections, which preferably are arranged parallel to one another. Thus, the entire wiper receptacle 20 or respectively the cavity 200 thereof is substantially of cuboid design. That means that said receptacle has longitudinal sides which are straight. If the bracket 14 is not folded onto the wiper receptacle 20, i.e. the tube holder 10 is open, the straight sections of the base 21 and the bracket 14 enclose an angle, which is shown in FIG. 1.

(7) The wiper receptacle 20 has a lateral stop 22, which is also 2 shown in FIG. 1. In so doing, the stop 22 is mounted to the base 21. The stop 22 extends substantially transversely to the base. In an advantageous manner, the stop 22 is arranged on the opposite side of the base 21 with respect to the closure 16. The wiper arm 12 can thus be pushed through an opening 11 into the tube holder 10 until said wiper arm abuts against the stop 22. The opening 11 is shown in FIG. 1. The opening 11 occurs if the bracket 14 is not folded onto the wiper receptacle 20. The opening 11 is thus present if the tube holder 10 is not closed. The stop 22 has particularly a free end 24. The fixed end thereof is mounted to the base 21. Ideally, the stop 22 has a contour that corresponds to that of the bracket 14. In the closed state, the bracket 14 presses against the stop 22. If a wiper arm 12 is now disposed in the wiper receptacle 20 and the bracket 14 is closed by the closure 16, the bracket 14 presses the stop 22 against the wiper arm 12, which leads to a firm fit of the wiper arm 12 in the tube holder 10.

(8) The bracket 14 has a brace 26 on the side which lies opposite the stop 22. The brace 26 extends on the inside of the bracket 14 in a manner that it originates on the inside of the bracket and ends on said inside of the bracket. In this way, a cavity is created which is formed between brace 26 and bracket 14. The brace 26 is flexible. If a wiper arm 12 is now disposed in the wiper receptacle 20 and the bracket is closed, the wiper arm 12 is then fixedly held in the wiper receptacle 20 on the one hand by the stop 22 and on the other hand by the brace 26. In so doing, the brace 26 shapes itself in accordance with the wiper arm 12 in the direction of the cavity 28. As a result, the cavity 28 is reduced in size. A further measure to better fix the wiper arm 12 in the cavity 200 is provided by the nose 34 on the inside of the bracket 14. The nose 34, as a small triangular structure on the bracket 14, is designed in such a way that the nose 34 projects into the cavity 200. If the bracket 14 is now closed, the nose 34 then presses on the wiper arm 12. It is also conceivable to form a plurality of noses 34 on the inside of the bracket 14. It is likewise conceivable to give the nose 34 another shape than a triangular one. Hence, circular or punctiform noses are conceivable.

(9) The closure as is illustrated in FIGS. 1 and 2 is a hook-shaped closure 16. In this case, a hook 30 is formed at the free end of the bracket 14. This bracket hook 30 engages around a base hook 32 which is formed at a free end of the base 21. This engagement is depicted in FIG. 2. An open closure 16 is illustrated in FIG. 1. At the free end 30 of the bracket 14, the bracket hook 160 points inwards with respect to the radial direction, while the base hook 161 points outwards at the free end 32 of the base 21. It is shown in FIG. 2 how the hooks 161, 160 engage in one another.

(10) The tube receptacle 18 is formed on the side of the base 21 which is directed radially outwards, wherein the tube receptacle 18 has a circular recess 38 which is open towards the outside. The tube receptacle 18 is formed by two extensions 36. The two extensions 36 have free ends 40 which are directed outwards. Starting from the base 21, the extensions are mounted with the fixed ends thereof to the base and they extend radially outwards so that the free ends 40 thereof are directed away from the base. Thus, a tube 7, shown in FIG. 3, can be inserted from the outside into the tube receptacle 18. The circular recess 38 can at least partially deviate from the circular shape thereof. Hence, straight sections are formed in the tube receptacle 18 or respectively the recess 38 particularly in the region of the closure 16.

(11) The bracket 14 extends, starting at one extension 36, past the stop 22. The bracket 14 is arranged such that said bracket is formed on the side of the base 21 which is opposite the tube receptacle 18. In doing so, the stop 22 and the bracket 14 are not connected directly to one another. The stop 22 and the bracket 14 are formed separately from one another, the stop 22 being mounted to the base, whereas the bracket 14 is formed on an extension 36.

(12) The tube holder from FIGS. 1 and 2 is made from plastic. The plastic of the tube holder 10 is flexible.

(13) An edge 44 is formed at the axial ends of the tube holder 10, said edge being directed outwards in the radial direction 2. A radius 46 is integrally formed on this edge 44, said radius being formed along the entire edge 44 or at least partially along the edge 44.

(14) A motor vehicle is depicted in FIG. 3, which has a wiping water tank 3, a windshield 4 and a wiper arm 12. A spray nozzle 5, which sprays the wiping water 6 onto the windshield 4, is arranged on the wiper arm 12. The spray nozzle 5 is connected to the wiping water tank 3 by means of the tube 7. The tube 7 is at least partially arranged on the wiper arm 12. The tube 7 is attached to the wiper arm 12 by means of the tube holder 10 according to the invention. In so doing, the tube holder 10 is mounted on the wiper arm 12.

(15) The features of all of the embodiments of the present invention can be combined with one another to form new embodiments according to the invention.
