  • Patent number: 7093330
    Abstract: A snap-hook that has a hook, forming a portion of an eye loop, and a lever that is pivotally movable relative to the hook. The lever forms a remaining portion of said eye loop with respect to the hook. A thumb tab is connected to the lever, and is positioned in a slot defined in the hook. The thumb tab is slidable in the slot relative to the hook, forming a release mechanism, such that the sliding movement of the thumb tab in the slot causes the lever to pivot relative to the hook to open said eye loop. The snap-hook has essentially broad, opposing, front and back sides, and relatively narrower edges, such that the back side of the snap-hook can be placed into the palm of a user's hand to hold the snap. The thumb tab is located on the front side of the snap-hook to allow simpler holding of the snap-hook and operation of the release mechanism with one hand while essentially eliminating swiveling of the snap-hook in the hand.
