The invention relates to a retaining frame (1, 11, 30, 35) for a support element (2, 21, 29, 33) of a sensor in a motor vehicle. Said retaining frame comprises a planar lower side (4, 22) which can be stuck on a window pane of a motor vehicle and an opening having at least one contact surface (5, 12, 31) for the support element (2, 21, 29, 33). In said contact surface, the support element (2, 21, 29, 33) can be positioned in a planar fashion relative to the window pane and against the contact surface (5, 12, 31). The frame also comprises a spring element (3, 13, 14, 15, 16, 24) by means of which the support element (2, 21, 29, 33) can be subjected to a force.
