摘要： This assembly comprises a collar (3) having splines cooperating with splines on the bolt (1) and lateral tabs (4) in contact with flat sides of the nut (2). This assembly further comprises at least one bent elastically yieldable locking element (5, 5') having a first branch (6, 6') trapped between a tab (4) of the collar (3) and a flat side of the nut, a second branch (8, 8') having an aperture (9, 9') through which extends the bolt and which has an edge engaged between screw threads of the bolt. By exerting a lateral pressure on the locking elements (5, 5'), the screw threads of the bolt are elastically disengaged.
