ABSTRACT:
A device for temporary retention of a lifting element on a metal surface of a form during the concrete pouring and setting phases of a prefabricated concrete member includes a part which is designed to form a depression in a concrete section and is equipped with magnets for attachment to a metal surface of a form. The device includes a part having a flat face, a recess terminating at a face opposite the flat face and orthogonal thereto desinged to permit passage with sealing action of a lifting element, and a slot terminating in the flat face. A locking element is mounted in the slot and pivots around an axis transverse to the slot. The locking element has a hook which forms a bolt designed to ensure retention of a free end of the lifting element when the locking element is in an unlocked position in the slot.
