Abstract
A releasable coupling assembly for support ribs associated with sign panels, and the like elongated support members. Force generated by a knob and threaded shaft is applied to a pressure plate through a lever arm. The lever arm is arranged so as to provide a reduced mechanical advantage which limits applied force to the rib. The lever arm may also be made resilient to limit force applied to a rib being clamped.
