Abstract: A generally U-shaped grab hook with an eye on one leg includes a safety latch which is pivotally mounted on the free end portion of the other leg to swing between latched and unlatched positions. When in its latched position, the latch retains a sling chain or the like in the throat of the hook and, because of the location of the pivot, any load placed on the latch by the chain tends to force the latch more tightly into its latched position. Spring-loaded detent balls are carried by the hook and coact with holes in the latch to hold the latch releasably in either of its positions and to require the latch to be positively pivoted from one position to the other.
