ABSTRACT:
A quickly detachable guard assembly for the tip of a chain saw guide bar, including a pair of wing plates hinged along one side and urged by a torsion spring to a clasping condition with the guide bar therebetween. A pair of pins projecting from the inner face of one plate pass through openings in the guide bar and are received in holes in the other plate to positively lock the guard assembly to the guide bar. A selectively operable latching arrangement allows the plates to be held apart against the urging of the spring urging to facilitate installation and removal.
