A lock for an adjustable wrench to lock the adjustable jaw of the wrench in adjusted position. The lock includes a slide mounted on the wrench handle adjacent the head of the wrench for longitudinal slidable and guided movement with a thumb receiving member at the end of the slide remote from the wrench head and an arcuately curved recess on the inner surface of the slide engaging with the rotatable worm wheel used to adjust the adjustable jaw of the wrench thereby retaining the worm wheel and adjustable jaw in adjusted position by frictional engagement between the slide and worm wheel. The slide includes a longitudinal slot receiving a pin which slidably anchors the slide to the wrench handle adjacent the wrench head with the end of the slide remote from the wrench head including a depending tapering projection to engage and be guided by longitudinal edge ridges or flanges normally provided on the handle of an adjustable wrench thereby maintaining the slide in longitudinal alignment with the wrench handle for movement toward and away from the rotatable worm wheel used to adjust the adjustable jaw of the wrench.
