A resiliently biased high strength corrosion treated guard is pivoted on the hook and has a hollow crown with slotted depending sidewalls. A winged finger piece is shaped to form an interlocked dovetail joint with the guard and the wings of the fingerplate overlap the slot of the guard and extend laterally therefrom adjacent the crown to reinforce the guard.
