Abstract: According to the invention, this device comprises:a grapnel-shaped element (6) comprising a central rod (6a) which is semi-rigid, that is to say exhibits a relative flexibility perpendicular to its longitudinal axis, capable of passing through the bone parts (2, 2a) to be secured, this rod (6a) being continued at one end via at least two branches (6b) which are curved through substantially 180 degrees and whose free ends are sharp-pointed, and the rod comprising, at its other end, a ring (6c) for pulling the grapnel-shaped element (6) through the bone parts (2, 2a) to be secured;a lock washer (8), anda metal sleeve (9) capable of being engaged on the rod (6a), until it comes into abutment against the lock washer (8), and of being crimped on the rod (6a) after the bone parts to be secured have been brought together and the grapnel-shaped element (6) has been tensioned.

Abstract: The assembly device of the present invention includes a body (10), a ring (11) and a nut (12);the body includes:a threaded upper portion (10a),two legs (15) delimiting between them a channel (16) for accommodating one (4) of the elongate components (4,5) to be assembled, these legs (15) being capable of moving apart or closer together;at least one bearing surface (19) formed on the lateral face of the body (10) or of the legs (15), forming an axial stop, anda transverse aperture (20) in which the second elongate component (5) to be assembled may be engaged;the ring (11) can be engaged over the body (10) until it comes to bear on the stop (19), and is dimensioned in such a way that in this position it lies around the legs (15);the nut (12) can be screwed onto the threaded upper portion (10a) of the body (10).
