A female part (1) can be locked in selected positions on a round rod (5). The female part includes a hollow passageway (2) into which a locking screw (3) can be screwed in a generally radial direction into engagement with the rod (5). When seen in cross section, the passageway (2) includes two flat surfaces (6) which slope towards one another symmetrically in relation to a diametrical plane (7). The angle (a) defines by the surfaces with the plane (7) lies between 2.5' and 15'. The locking screw (3) enters the passageway (2) in the wider part between the surfaces (6). <IMAGE> |
