ABSTRACT:
A unitary bowstring-holding member in the form of a frame having an integral pair of spaced, opposed resilient clamp jaws, the resiliency thereof being due to the nature of the frame. The device also includes a trigger member having a forked portion intercepting the frame and pivotably connected to one of the jaws, and a link pivotably connected to the other of the jaws and to the forked portion so that movement of the trigger member in a first direction (through the link) forces the jaws toward each other into a bowstring-holding closed position and so that movement of the trigger member in the opposite second direction permits sudden bowstring-releasing opening of the jaws.
