A snap hook 41 comprising a bi- ended base portion 43, a blade portion 45, a re-entrant portion 50 and a latch portion 47 is disclosed. The blade 45 is integral with a first end of the base, through the re- entrant portion, thereby providing the snap hook with an aperture 51 intermediate the base and the blade. The aperture has a mouth 55 and two integrally formed lips 53. The aperture is adapted to receive a substantially cylindrical portion of a retainer 59 therein. The latch 47 is integral with the second end of the base and thereby provides the snap hook with a hook 63 at the junction thereof. A free end 65 of the blade and a free end 67 of the latch are in distal relation to the base. A relaxed condition for the snap hook (full lines Figure 1) is defined to be when the distal end 65 of the blade is above the distal end 67 of the latch, in relation to the base. A locked condition for the snap hook (phantom lines Figure 1) is defined to be when the distal end 65 of the blade is positioned beneath the distal end 67 of the latch, in relation to the base. The lips 53 are adapted to lockingly retain the above-mentioned substantially cylindrical portion of the retainer 59 while the snap hook is in the locked condition and the blade 45 is in biased engagement with the latch 47. A ring 97 is selectively permitted to be secured to or released from the hook 63 by manipulation of the blade 45. <IMAGE> |
