In a coupling for the connection of a washing-liquid pipe in a motor vehicle to another component, a catching element ( ) designed for connecting two coupling parts ( ) has a shell ( ) of C-shaped cross section intended for gripping. Catching noses ( ) project radially inwardly from the shell ( ). By this, mounting and demounting of the catching element ( ) are especially simple.

Coupling for connecting two components conveying a medium

A nozzle assembly (,) for a washing nozzle (,) of a windshield washing system is pivotably mounted in a recess (,) of a body panel (,). The nozzle assembly (,) has an eccentric (,), by which the angle of inclination of the washing nozzle (,) can be set in relation to a windshield (,) to be cleaned. Tolerances of the nozzle assembly (,) and of the body panel (,) can thereby be compensated in a simple way.

Nozzle holder to be fixed to a motor vehicle

A cleaning device for a motor vehicle headlight lens, a washer nozzle (,) is arranged on a support (,) having tubes (,) which can be moved in the manner of a telescope. An outer tube (,) of the support (,) can be moved by an adjusting arrangement (,) having an electric motor (,). A connecting branch (,) for a washer fluid line (,) is latched to a fixed guide sleeve (,). As a result, the cleaning device is of particularly compact construction.

Cleaning device

In the case of a cleaning device (,) a washer jet (,) is arranged on a piston rod (,) which can be moved by means of an electromotive drive unit (,). A heating element (,), which is connected to a hollow cylinder (,) which is in a fixed location, is situated, in its illustrated position of rest, in the direct vicinity of the washer jet (,) and in this manner makes it possible for the washer jet (,) to be heated thereby preventing it from freezing up when ambient temperatures are critical. No electrical contacts are required on the moveable part of the cleaning device (,) because of the connection of the heating element (,) in a fixed location.
