Presented is an arrangement for coupling two rod-shaped prosthesis sections that displays a clamping sleeve having at its ends contrarotating internal threads that can be screwed with corresponding external threads of the prosthesis sections. To prevent loosening of the connection, the free ends of the prosthesis sections are provided with complementary, sloping contact surfaces which, when tightening the clamping sleeve, produce a loaded diagonal thrust and thereby place the screw couplings under load.
