ABSTRACT:
Improved locking wrenches are provided with adjustment screws having a head portion and a flange extension associated with the lower handle. A locking element is provided which serves to lockably engage a restraining element associated with one of the adjustment screw and the flange extension. In this manner, inadvertent release of the clamping force exerted between jaws of the wrench may be prevented since the lower handle is restrained from moving into its opened stated relative to the upper handle.
