Abstract
In a detachable connection for drill pipes and other objects which can be used in the sinking of boreholes, a sleeve part (21) has in the interior radially directed projections, the undersides of which at least partly form engagement surfaces for bearing surfaces on an insertion part (11) for transmitting axial tensile forces. The insertion part (11) is provided on the outside with radially directed locking pieces which in each case form the bearing surfaces with at least part of their front sides. At least one supporting surface for seating the insertion part (11) for transmitting axial compressive forces is located on the sleeve part (21). Furthermore, there are push-in parts via which a torque can be transmitted. <IMAGE>
