The second member has a cylindrical recess, at least one (two if two projections are present on the opposite member) longitudinal passageway(s) adjoining the cylindrical recess, and at least one undercut recess adjoining both the cylindrical recess and the passageway. A reversible rotation blocking mechanism is also present. Preferably, an axial cannula is present in the coupling. A kit and a method of surgery are also disclosed.
