A washer formed by two identical C-shaped sections having parallel upper and lower surfaces, two ends, an inside and an outside arcuate edge, the ends having a plurality of tabs and recesses that inter-digitate to form continuous surfaces. The outside arcuate edges have a slot adjacent to one end and a flap projecting from the opposite end. The flaps are inserted into the slots of adjacent sections to retain adjoining ends in fixed relation to each other. Additional grooves on the outside arcuate edge facilitate assembly using needle-nosed pliers.
