The invention concerns an arrangement for forming a scaffolding node with a cross-strut and a pole from the outer surface of which protrudes at least one projection extending radially to the pole axis. The projection has a recess into which a hook disposed on the strut end can be introduced from above. Disposed on the strut end is a wedge (47) which, in the position which it automatically assumes when the hook (7) has been introduced into the recess (4), protrudes to such an extent from the hook profile, below the recess (4), that it prevents a vertical movement of the strut end upwards through the recess (4). Before the hook (7) is fully introduced into the recess, the lower end of the wedge (47) projects laterally beyond the contour of the hook (7) and comes to rest on the recess edge. As the hook is introduced further into the recess, the lower end of the wedge (47) can be pushed upwards through the edge. |
