The connecting means include a threaded hole (4) extending from the bottom of a tapered recess (5) in the femoral end of the shank (2) or raspatory (10), and a threaded projection (7) provided on the ancillary tool and screwable into said threaded hole. The bottom of the tapered recess (5) in the raspatory (10) and the shank (2) has a shaped indent (9) of which the edge includes alternately concave and convex curved portions, and is engageable by a projecting indexing portion with a matching shape arranged on the end of the removable neck.
