Abstract: A ratchet-like wrench is provided with a wrench body having a fixed jaw and a two arm jaw pivotally mounted on the wrench body to define a spanner aperture with the fixed jaw. A two armed wrench handle is pivotally connected to the wrench body with one arm of the handle operatively engaging one arm of the pivotable jaw. A rocker element and a coupling element are pivotally connected to each other and to the fixed jaw and the pivotable jaw respectively to form a toggle-link linkage for moving the pivoted jaw into and out of operative position. A return spring is disposed between the coupling element and the pivotal jaw for biasing the pivoted jaw to the open condition and for preloading the coupling element and the rocker element toward a locking position. The coupling element is provided with a projection operatively engaged by the handle so that upon pivotal movement of the handle the rocker element and the coupling element can be moved into and out of alignment.
