The device has a stud (3) and an articulation axle (4) permitting free tilting of a panel (2) of a frame (1) from an inverse opening position to a closing position. The stud has a lug (16) which abuts on a cut off flange of an articulation end of the frame to lock the panel at a safe open upright position perpendicular to the frame when the panel is accidentally tilted from its inverse position. The axle and lateral opening ramps co-operate to avoid the panel extraction in the upright position, while permitting tilting of the panel to a closing position of the frame from the upright position. |
