Over a part of its axial length, the mounting projection (11) is concentrically surrounded by a sleeve-like portion (15) provided on the support arm. In its region which is not surrounded by the sleeve-like portion (15), the mounting projection (11) is provided with a peripheral groove (16) for winding up an overhanging free thread end portion (FE) which is not engaged by the catch means (12, 13, 14).
