摘要

The ring (4) has a contact face (5) locked against a part by axial displacement of the ring along a rod. An axial blocking unit is constituted of pins (9). Cylinder segments (13, 15, 17) are connected by a frangible attachment (12) and other frangible attachments that permit the segments to be radially separated from one another under an effect of predetermined pressure exerted against a ring face (6), where the ring face is arranged opposite to the contact face. The attachments are located between the blocking unit and the contact face, where the ring is made of recyclable semi-rigid plastic. An independent claim is also included for a fixation device for fixing a part comprising a part maintaining ring.
