Abstract: A connecting element for concrete or reinforced concrete structural members that are to be cast one after the other has a body (1) having at least one continuous threaded hole (nut 5). The body (1) is designed for releasable fastening to the shuttering for the structural member that is to be cast first of all. In this respect, the half, averted from the shuttering, of the threaded hole serves to receive an end, provided with an external thread, of a reinforcing part (9) that is to be embedded into the structural member that is to be cast first of all, and the other half of the threaded hole serves, after removal of the shuttering, to receive an end, provided with an external thread, of a reinforcing part (11) that is to be embedded into the structural member that is to be cast after that.
