A safety-hook construction comprises a hook-shaped body having spaced first and second legs which cooperate to define a mouth on the body, a closure member pivotally mounted on the body and a locking member pivotally mounted on the closure member. The safety hook is normally biased to a closed position wherein the closure member obstructs the mouth on the body, wherein the locking member engages the inner surface of the first leg to prevent the closure member from being pivoted inwardly, and wherein a pair of thumb tabs on the locking member extend outwardly along opposite sides of the first leg. The safety hook is movable to an open position by grasping the body in the hand and drawing the thumb tabs along the first leg so that the locking member is pivoted toward the closure member and the closure member is pivoted inwardly until it no longer obstructs the mouth.
