ABSTRACT:
A coupling for clamping metallic scaffold tubes has two levers pivotally mounted on a common hinge and arranged to be locked by a wedge when they surround the scaffold tube. One of the levers is provided with a second hinge pivotally supporting a yoke which in turn supports the wedge. The thickened formations are provided on two opposite faces of the bars constituting the yoke, the formations preventing the wedge which is formed of sheet metal from slipping out of the yoke.
