Claims

1. A connecting device comprising a pipe socket and a hose made of rubber-like material, wherein the pipe socket and the hose abut each other in a sealing zone which at least over a part of a length thereof is surrounded by a hose reinforcement that forms part of a geometric locking configuration for holding the pipe socket and the hose together.

2. The connecting device according to claim 1, wherein the hose reinforcement has a stronger deformation resistance than the hose.

3. The connecting device according to claim 1, wherein the hose reinforcement has a heat expansion coefficient which is about 60% to 150% of the heat expansion coefficient of the pipe socket.

4. The connecting device according to claim 1, wherein the hose reinforcement is connected with the hose in a positive locking manner.

5. The connecting device according to claim 4, wherein the hose reinforcement engages in the sealing zone in a recess on the circumference of the hose.

6. The connecting device according to claim 1, wherein the hose reinforcement is connected with the hose.

7. The connecting device according to claim 1, wherein the hose reinforcement has a fiber inlay or a textile inlay which is embedded in the material of the hose.

8. The connecting device according to claim 1, wherein the hose reinforcement is formed by a bearing ring which encases the hose at least over a length of the sealing zone.

9. The connecting device according to claim 8, wherein the hose reinforcement has a locking surface which proceeds essentially vertically to the center axis of the pipe socket on which a locking element engages for producing a form-fitting connection between the hose reinforcement and the pipe socket.

10. The connecting device according to claim 9, wherein the hose reinforcement has a circumferentially extending groove (15), wherein a wall of the groove forms the locking surface.

11. The connecting device according to claim 9, wherein the locking surface is comprised of an elastic ring.

12. The connecting device according to claim 8, wherein the hose has on its outside at least two radially projecting cams and openings between the cams, wherein behind every cam there is a clearance and wherein the hose reinforcement has at least two inwardly projecting juts which fit through the openings and into the clearances.

13. The connecting device according to claim 12, wherein the hose reinforcement and/or the hose provide a locking jut which forms a pressure point that needs to be surpassed when twisting the hose reinforcement against the hose.

14. The connecting device according to claim 1, wherein the combination of hose and hose reinforcement provide at its end facing the pipe socket a conical expansion.

15. The connecting device according to claim 1, wherein the pipe socket has a circumferential projection which is beveled at its front end facing the hose.

16. The connecting device according to claim 1, wherein the projection has on its backside facing away from the hose a socket locking plane.

17. The connecting device according to claim 16, wherein the pipe socket has a boundary jut at a predetermined distance from the backside.

18. The connecting device according to claim 1, wherein the hose reinforcement has several axially positioned and radially swinging fastening fingers and an axially adjustable locking ring which counteracts in a locked position a deformation of the fastening fingers.

19. The locking device according to claim 1, wherein the locking ring is engageable in the axial direction with at least one fastening finger.

20. The locking device according to claim 18, comprising at least one support finger between at least two fastening fingers.

21. The connecting device according to claim 18, wherein the fastening fingers are attached to the pipe socket.

22. The connecting device according to claim 18, wherein the fastening fingers are attached to a hose sleeve and elastically hooked to the pipe socket.

23. The connecting device according to claim 1, wherein the geometric fastening configuration is provided in the form of a bayonet connection.

24. A connecting device according to claim 1, wherein the pipe socket has a diminution taper at the end thereof which is plugged into the hose.

25. The connecting device according to claim 1, wherein the hose expands in the area of the sealing zone at its end pushed onto the pipe socket.

26. The connecting device according to claim 1, wherein the hose and/or the pipe socket has in the area of the sealing zone at least one bead.

27. The connecting device according to claim 1, wherein the hose has in the sealing zone a sealing lip which cooperates with the pipe socket.

28. The connecting device according to claim 1, wherein the hose and the pipe socket have in the sealing zone a frontal and a circumferential contact component.

29. The connecting device according to claim 28, wherein the pipe socket has a frontal circumferential groove in which the hose engages with its frontal circumferential jut.

30. The connecting device according to claim 29, wherein the groove has with increasing depths a decreasing width.
