Abstract: In a mounting device with at least one mounting aperture that is situated in a flange and penetrated by a mounting screw, it is proposed to provide the flange with at least one slot on the edge of the mounting aperture. Furthermore, the diameter of the mounting aperture is smaller than the outside diameter of the screw thread of the mounting screw. Consequently, the elastic material properties of the flange are utilized in a particularly advantageous fashion because a certain force needs to be exerted in order to screw the mounting screw into the mounting aperture or out of the mounting aperture. This ensures that the mounting screw also cannot readily detach from the mounting aperture during long-lasting vibrations, i.e., it is captively held in the mounting aperture.
