Abstract

In order to connect the core undetachably to the holding element in the case of a pin-type holding element for an orthopaedic holding system with an elastically compressible, head-shaped widened portion and with a central opening, into which a core may be inserted, which prevents an elastic compression of the head-shaped widened portion by filling out the central opening in the region of the widened portion without expanding this, it is proposed that the core is displaceable in the opening between a locking position, in which it fills out the central opening in the region of the widened portion, and a release position plunging deeper into the central opening, in which it releases the central opening in the region of the widened portion and thus allows its elastic compression
