A safety snap hook comprising:
- a) a J-shaped shank having at one end thereof a hook including a tip extending therefrom defining a hook mount;
- b) load supporting means at the other end of said shank for attaching a load;
- c) a spring biased latch member having one end pivotally mounted on said shank and the other end free for selective engagement with said tip to close said hook mouth for a closed position, and to open said hook mouth for an open position;
