The wedge (15) includes at least one lower rearwardly projecting fastening flange (31) delimiting a transverse groove (33) issuing at each transverse end; at least one transverse end of the rear flange is provided with a canted surface (35b) inclined along an angle determined in relation to the transverse direction of the wedge, the canted surface (35b) and the portion adjoining the rear flange forming an outwardly convex dihedron. This canted surface (35b) permits the disengagement by the upward escape of the flange (31) for a twist of a predetermined amplitude, in a given direction along an angle that is smaller than the maximum angle of twist wherewith the device still exerts an elastic restoring action on the wedge.
