Abstract: A cleaning device (1) for a lens (2) of a headlight of a motor vehicle has two telescoping tubes (6, 7), the outer tube (6) holding a spray nozzle (9). The outer tube (6) is also surrounded by a protective tube (8) to be fixed in the motor vehicle. When the outer tube (6) is pulled out (9), the spray nozzle is displaced over the lens (2). The connections of the tubes (6, 7) are reliably protected from dirt accumulation.

Abstract: The connection element includes a tubular coupling which is connected on the inside at one end to a hose which has, on its side facing away from the hose , at least one clearance, of which the lateral edges running parallel to the longitudinal axis of the tubular coupling run, in the cross section of the respective clearance, so as to widen conically with respect to one another from the inside outward. The tubular coupling has at the other end, on the outside, at least one first projection which bears against one end face of a snap ring which is arranged between the at least one projection and the one end of the coupling, around the coupling on the outside.

Abstract: In a plug-in connection (1), in particular for fluid lines, which comprises a part of the connection (2) to be inserted and a receiving part of the connection (3), between which a seal (10) can be clamped and which are able to be releasably connected to one another by flexible snap-in elements (7, 18) in a snap-in position, the seal (10) can, be clamped between a front portion (4) of the part of the connection (2) to be inserted and an abutment (11) in the receiving part of the connection (3) and the distance of the snap-in elements (7) of the part of the connection (2) to be inserted from the front portion (4) of the latter is dimensioned such that the snap-in position is reached after slight axial compression, and if need be radial compression, of the flexible seal (10).
