Claim:
A lock for securing a wear member to earth-working equipment comprising: a plurality of bodies interconnected for pivotal movement about a pivot axis between a retaining position where the bodies are aligned in a generally linear orientation and the lock holds the wear member to the earth-working equipment and a release position where the bodies are pivoted to a relative angular orientation and the lock can be removed to permit removal of the wear member from the earth-working equipment, wherein the lock has a length in a direction transverse to the pivot axis that is greater in the retaining position than in release position, and wherein each body provides generally the same resistance in preventing removal of the wear member from the earth-working equipment; and a retainer to prevent the bodies from moving about the pivot axis out of the retaining position, wherein the retainer is a threaded member that engages each of the bodies in the retaining position and releases at least one of said bodies in the release position.
