Abstract: A fixing apparatus for fixing two radial arms of a drive mechanism of a wiper device to a body shell element configured to be disposed vertically on a motor vehicle has a plug-type cylindrical body configured to be partially inserted into a first opening on the body shell element. The plug-type cylindrical body has a locking mechanism configured to prevent the plug-type cylindrical body from disengaging from the first opening on the body shell element. The locking mechanism has a secondary element connected to the plug-type cylindrical body by a material bridge. The secondary element is configured to be partially inserted into a second opening on the body shell element. The secondary element is configured to be unlocked from a locking position by applying transversal and then longitudinal forces on the secondary element in a longitudinal axis defined by the at least one plug-type cylindrical body.

Abstract: A method is disclosed for assembling a windscreen-wiper mechanism having a support plate on an internal face of a body structure element that extends globally vertically at a rear of a motor vehicle. The method includes the steps of positioning the support plate relative to the internal face of the body structure element and joining the plate to the internal face of the body structure element. The positioning step includes moving the plate relative to the body structure element along a first direction, and the joining step includes rotating the plate about the first direction.
