1. A snap hook comprising a ring having a straight side, interrupted by an opening defined by first and second ends,
wherein said opening is closed by a spring closing element having an open position and a closed position, said snap hook comprising a separation lever, dividing a space enclosed by the ring in two separate areas, wherein said lever is independent from said closing element and wherein said closing element and said separation lever are hinged to a same hinge, wherein the closing element comprises a tubular body, whose length is larger than the first straight side opening, the tubular body being hinged with the same hinge at the first end of the first straight side, wherein at said same hinge, the tubular body has a longitudinal through-groove, transversally drilled by a bore, said groove bridging the first end of the straight side of the ring; wherein said first end has a transverse through-bore and a slot on the symmetry plan of the snap hook ring; and wherein the lever includes at one end a tab having a through-bore, a pin being inserted through said bores of the tubular body, of the first end of the straight side and of the tab, respectively, when they are aligned, to implement the same hinge. |
