To permit absorption of sudden impacts or shock overloads, or gradual overloads, on a cable stretched to retain stones, rocks or snow masses, for example in road or railway cuts, a tube is bent to form an open loop, the end portions of which are held together by a clamp so that the end portions are frictionally engaged against each other, and the cable is threaded through the tube. Upon overload, the tube can plastically deform, thereby reducing the diameter of the loop or ring formed thereby, and accept overloads without overloading or unduly stressing the cable.
