The frame is fixed to an external plate (4), and has a locking screw (14) located in a prismatic bulge (13) that is disposed on one side of the frame. The screw is activated from the exterior to be moved such that a head (16) of the screw is located at the interior of a circular opening (17) to prevent all the movement of the head and detachment or separation of the head from the frame.</p> |
