A connection element comprises a bolt (6, 7, 8, 9) which by means of a sleeve insert (3) can be fastened rotatably to one end of the rod (11), as well as a sleeve (12) into the axial throughbore of which the bolt is partly inserted, to transmit, sliding axially, a rotary movement of the sleeve (12) to the bolt. With this, the through-bore is only in the front part of the sleeve (12) designed such that it can transmit a rotary movement of the sleeve (12) to the bolt. At the rear part of the sleeve (12) the through-bore has a circumference which is larger than the circumference of the complementally shaped front part of the through-bore. The bolt is pushed out of the sleeve (12) by a spring (13). The front end part (9) of the connection element can be fastened to a junction part (10) of the three-dimensional framework. |
