The present invention is a safety hook ( 12, 12 ') having a wire spring latch ( 26, 26 '). The wire spring latch ( 26, 26 ') is a wire loop pawl. The safety hook ( 12, 12 ') is made of a heavy gauge wire form material, which is preferably bent only to form first and second ends ( 14, 14', 16, 16 '), a chain link securing end ( 14, 14 ') and a hook opening end ( 16, 16 '), respectively. The wire loop pawl ( 26, 26 ') is preferably a rod of elastically deformable material, bent to form an open loop ( 28, 28 ') and bent-over ends ( 32, 32', 34, 34 ') about which the pawl ( 26, 26 ') pivots with respect to the body ( 12, 12 '') of the safety hook ( 10, 10 ') when the latch ( 26, 26 ') is deformed and forced away from a distal end ( 38, 38 ') of the hook opening end ( 16, 16 ') of the safety hook ( 10, 10 '). The bent over ends ( 32, 32', 34, 34 ') of the wire loop pawl ( 26, 26 ') are not coaxial. The wire loop pawl ( 26, 26 ') may be deformed in such a way as to open the safety hook ( 10, 10 '), but the latch ( 26, 26 ') is heavily spring biased up against an inside ( 37, 37 ') of the distal end ( 38, 38 ') of the safety hook ( 10, 10 ').
