A wrench stop on a wrench having opposite ends that include respective engagement apertures for fitting with a head member to be engaged by the engagement aperture. A slide member constructed and arranged for mounting adjacent to the engagement aperture and including an end catch. The slide member has retracted and extended positions. The slide member, in the retracted position thereof, has the end catch disposed away from the engagement aperture, and in the extended position thereof, has the end catch disposed over the engagement aperture so that the wrench piece does not disengage from the head member. |
