Abstract: Assembly for the production of a wiping system, comprising a terminal part (2) of a wiper arm designed to move a wiper blade (3) over the surface to be wiped and a hydraulic connector (30) comprising at least one piping element (31, 32) for conveying a liquid to the wiper blade (3), the said terminal part comprising at least one means (8) for supporting the said hydraulic connector ensuring that it is held longitudinally with reference to the wiper arm. It is characterized in that the said supporting means allows a movement of the said hydraulic connector (30) in a direction convergent with the longitudinal direction.

Abstract: An air guide box, particularly for installation in motor vehicles, has a part permanently located in a holder and a removable cover part for the replacement of, for example, an air filter insert. Actuating elements are fastened to the removable cover part and each of which operates an air butterfly also supported in the removable cover part. In order to avoid having to release specifically conduit connections required for the control of the actuating elements during the removal of the removable cover part, the conduit connections are run in sections in a wall of the removable cover part and of the permanently located part, respectively. A plug-in connection is provided in the joint between the two parts of the box, and is separated during the removal of the removable cover part and joined together again when the cover part is replaced. The removable cover part can be configured as a frame for adjustable plates of a cooling air guide on a fan.
