Abstract
A socket and/or insert ( ) for accommodating a fastener head is inserted in a screwing attachment ( ). The socket and/or insert ( ) comprises two jaws ( ) which engage in a tubular holder ( ) in which they are locked against rotation. The jaws can slide in axial direction relative to the holder ( ). In their one end position, the jaws ( ) can be forced apart in radial direction for insertion of a fastener head. Under the effect of axial force in the direction of the arrow ( ), the jaws ( ) are pressed into the holder ( ), whereby the jaws are necessarily squeezed toward each other in radial direction by virtue of the tapered camming faces ( ), so that the inserted fastener head becomes firmly clamped.
