Abstract

1. Arrangement for attaching a pre-assembled concrete unit to a lifting device comprising of two elements (1, 2) movable relatively to each other wherein first element (1) is having an eye or similar for the attachment to the lifting device and a slot open on the lower side to receive a supporting stirrup member (21) connected to the pre-assembled concrete unit and furthermore having a circular guidance (5) for the second element (2) being designed as a movable remote-controlled latch and a tongue (22) protruding in locked position into a slot (20) so that during lift stirrup (21) rests on tongue (22) including a downward safety lip (3) on a second element (2) and a cup (4) to receive said safety lip which is provided on the first element in such a way that effective height of said safety lip and effective depth of cup respectively is approximately equivalent to play of second element (2) in guidance (5) and an operating arm (7) - visible from the outside - is attached to the second element (2) interacting with a snap safety lock (6) for both positions of the second element (2) and giving indication of said positions.
