Abstract

Arrangement for force transmission, in particular in underpinning drill rods. In order to be capable of safely taking up even large loads in a detachable connection between an elongate piece, in particular part of a drill rod, and a counter-support, the piece 10 has at least two support surfaces 8, 9 located at a distance from one another in the axial direction, and holding members 20, 22 which form an intermediate member between the piece 10 and the counter-support, holding surfaces 21, 23 corresponding to these support surfaces 8, 9 being located at a distance from one another. <IMAGE>
