Abstract:
1. A connecting element for mechanically connecting constructive elements, in combination with at least one constructive element, said connecting element comprising an elastically deformable tensioning element applying a holding force in an elastically expanded state onto the at least one constructive element, thus generating a frictional connection of said at least one constructive element with at least one of said tensioning element and another constructive element, wherein said tensioning element has a length in the axial direction, and comprises a spring material consisting of a superelastic shape memory alloy elastically expandable, said tensioning element being in a stress-induced martensitic state to produce the holding force, and wherein the tensioning element comprises a clamping sleeve, into which the at least one constructive element is inserted in the axial direction, whereby the clamping sleeve is elastically deformed and pre-tensioned by compression in order to insert the at least one constructive element, and the clamping sleeve is partially relaxed for realizing the connection.
