Detachable linking system for two components

A detachable linking system for two components, of the type comprising a linking mechanism for said components and a control device for said linking mechanism so as to cause the detachment of said components,

• said linking mechanism being of the elastic deformation type and comprising, according to a longitudinal axis, at least:
• one rod having a widened end being longitudinally slit and elastically deformable, and fastened, at its other end, to one of said components;
• one axially movable needle having an end being introduced into said widened end of the rod for holding it in an open position and the other end being connected to said control device;
• and
• one axial hole body, fastened to the other component and surrounding said cooperating ends of said rod and of said needle, being axially linked to the latter and comprising, in said hole, an annular axial abutment against which said widened end of said rod is applied;
• and
• said control device being of the axial shift type, according to said longitudinal axis, and acting on said needle of the linking mechanism for moving it away from said widened end of the rod and, through the action of said abutment of the body linked to said shifted needle, for having said elastically deformable widened end switching from its open position to a closed position and enabling the relative crossing of said rod through said abutment of the body,
• said system being characterised in that said needle is held axially in position with respect to said rod by a deformable ring carried by a clamping member of the component on said body and applying against an external annular edge of said needle.
