摘要

The clamping device comprises two clamping jaws (18) which come into contact through their internal peripheral surface (33) with the element to be clamped. Elastic rods (34,36) are interposed circumferentially between adjacent lateral surfaces (28) of the jaws in order to apply their spring force radially outwards in the direction of opening of the clamping device.
