Abstract:
1. A detachable linking system comprising: a base; an acceleration system; a guidance system interacting with the acceleration system; a linking mechanism linking the base and the acceleration system, comprising: a control device; a rod having a widened end being slit longitudinally and elastically deformable and fastened, at its other end, to one of said base or acceleration system; a needle, movable axially, having an end being introduced into said slit of said widened end of the rod for holding the slit at the widened end in an open position and the other end being connected, directly or indirectly, to said control device; an annular elongated body comprising an axial hole fastened to the other one of said base or acceleration system and surrounding said widened end of said rod and said end of said needle; said annular elongated body being axially linked to the needle and comprising, in said axial hole, an annular axial abutment member comprising a bore against which said widened end of said rod is applied; a deformable ring comprising an outside diameter and an inside diameter defining a ring surface therebetween positioned adjacent a shoulder linked to said annular elongated body having a bore, said ring having a first configuration in which said ring surface abuts the shoulder linked to said annular elongated body and a second configuration in which said outside diameter is deformed and said ring passes through said elongated body bore; and wherein said control device is axially movable to act on said needle to move said end of said needle away from said widened end of the rod and, through the action of said abutment member linked to said needle, for forcing said elastically deformable widened end to change from its open position to a closed position to enable the widened end of said rod to pass through said bore of said abutment member of the body.
