Abstract
The invention concerns a coupling for the connection of scaffolding components having a coupling mouth in which the closing motion of the jaws is induced by a tensioning means configured as a wedge with ribs running diagonally against its direction of motion during tensioning. In the present invention the ribs (39, 49) work together with teeth (32, 44) on a moveable jaw (20) of the coupling mouth, and the wedge (30) has a curved cross section.
