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.
Pour absorber les impacts soudains, les surcharges ponctuelles et les surcharges graduelles sollicitant un câble établi pour retenir des pierres, des massifs rocheux ou des accumulations de neige et ainsi protéger des routes ou des voies ferrées en tranchée par exemple, on enfile ledit câble dans un tube cintré en boucle ouverte, les extrémités libres du tube étant maintenues ensemble en contact frottant au moyen d'une bride de serrage. En présence d'une surcharge, le tube subit une déformation plastique entraînant une réduction du diamètre de la boucle ou de l'anneau qu'il forme, ce qui pour effet de soustraire le câble à une surcharge ou un effort excessifs.
