1. The invention concerns a coupling for combined tools, stretched axially by means of a stretching and locking unit installed in one of the fasteners; the fasteners include front retaining surfaces and one of the fasteners is located in a socket made in the body of the second fastener; whereas, the socket and the body of fastener located in this socket both have matching and aligning surfaces, characterised in that the stretching and locking unit is a screw (8), one threaded end of this screw is driven into the fastener body (1), whereas the other threaded end, of opposite thread direction in relation to the first end of the screw, is driven into a sleeve (9) ended with a flange (10) which locks the coaxial cylindrical pressure in relation to it, cylindrical resistance flange (13) made inside the body of the second fastener (2), whereas, the resistance flange (13) matches the locking flange (10), while the sleeve (12) has an angular cut-out (11), into which a revolution limiter (12) for the sleeve (9) protrudes, the limiter (12) is joined with the fastener body (1).<IMAGE>
