摘要

The device (4) has an auxiliary case (5) in which a hook bolt (6) is slidingly mounted between a locking projecting position and an unlocked service position. A reversing device (20) subjects a trestle (7) to displacement in the auxiliary case in a direction that is opposite to a direction of actuation rods that are cooperated with the trestle. The trestle is mounted in axial translation in the auxiliary case in a direction perpendicular to a pivoting axle (10) of the bolt.
