<p>Device for coupling scaffolding elements (4/304) with uprights (3) in a scaffolding or the like. A gripping part (6) which at its upper end is open in the use position and is connected to the upright has a first gripping surface facing the upright extending from the upright. A hook-shaped part (7) attached at the scaffolding element (4) is hooked into the gripping part and supported by it. A movable locking device (37) which can be moved between a locking position and a position for releasing the coupling device has a first tightening part (38) and a second tightening part (50). The first tightening part exhibits a forward tightening surface which is contactable against the upright (3). The second tightening part forms a locking wedge and in the position obtains support from a support surface (53) facing the upright of the hook-shaped part (7). The locking wedge is tightened by locking action by means of a forwards facing tightening surface (51) facing the upright against a tightening surface (46) facing away from the upright on the first tightening part. In the release position with a portion of the first tightening part (38) this supports the second wedge-formed tightening part (50) in its release position.</p> |
