A suspension element for suspending a load and absorbing energy if the load is increased suddenly above a predetermined minimum includes a normally rigid ring that is permanently deformable under an applied load above said minimum. Diametrically opposite areas of the ring are connected to a support and a load, but the opposite sides of the ring between those areas are free of the connecting means and subject to being pulled toward each other if the load suspended by the ring suddenly increases beyond the predetermined miminum and elongates the ring in the direction of the movement of the load. The energy required to thus deform the ring is absorbed by the ring.
