A screw (7) is used as part of a securing mechanism (5) with a fixture (1), particularly with a swiveling arm (2), for a support system to secure, in particular, a medical or salon-technical device, with a holding part (3) and a mounting part (4) mounted on the holding part (3). The screw (7) is screwed into the holding part (3) or the mounting part (4), wherein the screw head (8) projects into a groove (9) of a bushing (14) of the other part (3, 4), i.e. of the mounting part (4) or the holding part (3), and wherein the screw head (8) can move freely in the groove (9) when there is a relative rotation between the holding part (3) and the mounting part (4), and wherein the groove (9) is bordered by an upper surface (6). If there is a failure in the connection between the holding part (3) and the mounting part, for example, if the securing ring (11) fails, the surface (6) impacts the screw head (8). In this manner, the holding part (3) is held on the mounting part (4). |
