Abstract: A clamp and installation tool combination wherein the clamp portion comprises an elongated pin having a hook at both ends and containing multiple circumferential notches along its shaft. A clamp button with a central through-hole is mounted on the shaft of the pin and engages the notches so as to produce a ratchet-type mechanism that permits the motion of the button only in the direction of the distal end of the pin. The installation tool consists of a syringe-type applicator having an outer barrel containing a pin retention clip designed to engage the hook at the proximal end of the pin, so that the pin cannot move in relation to the barrel of the tool.
