The device (18) for clamping and locking the clamping collar includes a screw (22) located in a transverse direction with respect to the articulated elements of the collar and engaged through two blocks (19, 19') bearing on two articulated elements of the collar including two guide journals (20a, 20b) each engaged and held in an opening in a rod (26a, 26b). The openings (27a, 27b; 28a, 28b) form a pair (27a, 27b) of circular openings and a pair (28a, 27b) of oblong openings. Nuts (25, 25') make it possible to tighten and lock the collar. The clamping collar additionally includes a blocking device (31) consisting of a support (33) including a spacer piece (34) through which an opening passes and which includes parts (35a, 35b) for engaging on the rods (26a, 26b), a lock nut (37) mounted so that it can rotate in the opening of the support (33), means (41) for blocking the lock nut (37) in terms of rotation and in terms of axial translation, and at least one blocking finger (44a, 44b) mounted so that it can pivot on the support (33). <IMAGE> |
