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.
