<p>The case (1) has a cylindrical skirt (32) perpendicular to a base (31), and a retaining device for retaining the case in a hole. The device has radial tabs (36) protruding from the skirt. A flat rim (41) is provided on an external edge of the skirt. A fixation screw fixes a plate of an electrical apparatus and cooperates with a screwing hole (24) formed in a rotating ring (2) e.g. split ring. The ring is axially locked in the skirt. The screw allows passage of the rim from one axial position to another position and fixation of the plate in a selected orientation with respect to the case.</p> |
