A fastening construction, in particular for a wing mirror unit of a motor vehicle, comprising a base part (1) which can be fixedly connected with a vehicle, and a rotation part (3) which is arranged to be coupled with the base part (1) and which in coupled condition constitutes a central shaft for pivotally bearing-mounting a wing mirror unit. The base part (1) and the rotation part (3) are provided with at least one projection and groove pair (19, 20) cooperating as a bayonet catch, such that the rotation part (3) can be displaced towards the base part (1) and that when the projection and groove pair are in engagement, the rotation part (3) is pivotable about the geometric axis (2), and, after passing an intermediate angular position (13), through cooperation of the projection and groove pair (19, 20), the rotation part (3) is locked relative to the base part (1), axially along the geometric axis (2). The rotation part (3) and the base part (1) are further provided with blocking means (4, 6) which in a second angular position (5b) restrain the rotation part (3) from rotation relative to the base part (1) about the geometric axis (2). |
