A joint endoprosthesis and an instrument for knocking it in or out, which are provided for mutual connection with collaborating ribs and grooves, on the one hand, in a fork arranged on the end of the instrument shaft and, on the other hand, on the neck of the prosthesis, the direction of the instrument shaft being transverse to the plane of the fork. To obtain a positive, play-free and sensitive connection between the instrument and the prosthesis, the end of the instrument shaft is taken as a locking pin through a threaded bore in the fork and the prosthesis contains a locking recess for receiving the locking pin.
