At the end of the guy rope above the shock absorber there is a cone, which is linked to the lock of the carabiner, detaching it from the guy rope. The grab hook has inner radius which is 1.5...2.0 times larger than the radius of the guy rope on the diameter of the cone. The housing of the hook is in form of a cylinder with a limiting fender bar inside on the upper end, in which there is a floating plunger with a reciprocal limiting fender bar, under which there is spring with support at the butt-end of an inner cylinder with loops for tying the chord of the safety belt. The top part of the plunger goes into the cavity of the hook, and the bottom part is in form of cone-shaped cup with prong-shaped long slots, through which pass spring loaded pins, passing through openings in the inner cylinder and housing of the hook. There is a rod on the axis of the plunger in the cone-shaped cup.
