An articulated lock for securing a wear member to earth-working equipment includes a plurality of bodies interconnected for pivotal movement between an extended orientation with the bodies aligned and a retracted orientation with the bodies folded. The lock in the extended orientation can engage an opening of the wear member at an inner hold position to secure the wear member to the earth-working equipment or an outer release position. In the folded orientation the lock disengages from the opening of the wear member. Each body has a slot and a tab and, in the extended orientation, the tab of each body is received in the slot of the other body to limit separation of the bodies.
