摘要

The stop (1) has a frangible locking unit (7) to lock a hollow body (5) relative to a support (3) along a support direction (X). The unit has a base (9) with a support face (11) turned opposite to the direction, and the body is supported against the face under a stress along the direction. A frangible axle (13) of the unit is integrated with a central zone (15) of the face, and broken when the stress is higher than a preset limit. A blocking unit blocks the axle relative to the support along the direction, and has an orifice (19) in the support and a retaining bar (17) integrated to the axle.
