Abstract
A snap hook having a J-shaped body, a gate that is pivotable about a pivot point that is near the first end of the shank, and a movable locking pin located near the second end of the shank. The locking pin is moved by least one parallel bar that is generally parallel to the shank and extends along the shank. Connected to the locking pin is a movable thumb grip that when moved urges the parallel bar to move the locking pin. The locking gate further having a recessed portion positioned near the second end of the shank and a closure portion positioned near the nose of the hook body, the closure portion and the recessed portion being at about the same distance from the pivot point, the recessed portion being adapted to cooperate with the locking pin so that when the locking pin is moved by the parallel bar the gate is released so that the gate can pivot about the pivot point.
