A tension shock absorber comprises a length of music wire, one end of which is passed through a hole in an anvil the diameter of which conforms closely to the diameter of the wire. The portion of the wire which has not passed through the anvil is plated with a frangible metal. Excessive tension forces applied to the unplated end of the wire cause the anvil to peel the plating from the wire. A fixed sleeve closely surrounding the plated portion of the wire a short distance from the face of the anvil prevents premature propagation of peeling.
