ABSTRACT:
A plastic protective gripping member or guard fits on the jaw of a Vise-Grip type locking wrench whose jaws have lateral protuberances at their tips. The gripping member can be in a form of a block or cup having a slot with internal recesses on each side wall. The gripping member fits onto the jaw and permits swiveling about a transverse axis. The gripping member is installed by pushing it onto the jaw tip and twisting it 90 degrees. Nylon is a perferred material because of its comparatively high coefficient of friction even when wet or oily. The gripping surface can be concave, ridged, or flat.
