Abstract

The invention concerns an assembly for forming a scaffold joint with a transverse brace and posts having at least one projection extending radially with respect to the post axis out from its outer surface, the protrusion having an opening into which a hook disposed on the end of the brace can be introduced from an upper direction, wherein a wedge (47), disposed on the end of the brace, is sufficiently separated from the contours of the hook in its position automatically assumed below the opening (4) subsequent to introduction of the hook (7) into the opening (4) to block motion of the end of the brace in the upward direction through the opening (4), wherein the lower end of the wedge (47) projects in a sideward direction beyond the contours of the hook (7) prior to complete introduction of the hook (7) into the opening and seats on the edge of the opening and, with further introduction of the hook, can be displaced by the edge in the upward direction.
