A hook (22) and an eye (24) are integral with and located at opposite longitudinal ends of a body (26). The hook (22) includes a tip (58) spaced from the body (26) and defining a mouth (30) for attachment of the hook (22) to a ring or other object. A lock pin (28) mounted in the body (26) moves axially between a closed position engaging the tip (58) of the hook (22) and an open position. The body (26) has a flat, easily gripped shape with a button (32) at one side movable in a transverse direction. A cam system (90) translates transverse button movement into axial movement of the lock pin (28), and provides a decreasing force-displacement characteristic. The hook (22) is designed to break to prevent user injury in the event of excessive force, and includes a ramp surface (62) facilitating detachment of the hook. |
