A caliper-jaws type release which includes a cam-shaped pin for pivotally holding one of two opposing jaws in the release holder. The cam-shaped pin has a head portion, an eccentric middle portion of smaller diameter than the head portion and a concentric end portion of smaller diameter than the middle portion. The head portion has a recess in its top surface for receiving a lever having a complimentary projection. Inserting the lever into the complimentary recess permits the cam-shaped pin to be rotated. The eccentric portion pivotally engages the jaw. Rotating the cam-shaped pin with the lever causes the jaw to change position relative to the opposing jaw.
