Abstract

A detachable fastener includes a screw element and a securing ring. The screw element and the securing ring each include cooperating wedge-shaped surface tooth arrangements and two different pairs of stop surfaces. The wedge-shaped surface tooth arrangements face one another and form sliding surfaces sliding upon one another in a loosening direction of rotation resulting in an increase of the axial force. The first pair of stop surfaces transmits torque in a tightening direction of rotation. The second pair of stop surfaces transmits torque in a loosening direction of rotation. The stop surfaces are arranged with a clearance existing between one another such that the wedge-shaped surface tooth arrangements can slide upon one another without skipping.
