An anti-torque safety hook includes a main body (10), a gate member (20), and a detent member (30). The main body (10) has a hook opening (15) passing through the front and back sides thereof, a passage (16) communicating to the right side of the hook opening (15), a female buckle (17) arranged on the passage (16), a connection unit (13) arranged below the hook opening (15), and an energy absorption area (E) arranged on the left side of the hook opening (15). The gate member (20) has a first end mounted on the main body (10) and a second end comprising a male buckle (25), adapted for detachably coupled with the female buckle (17), so as to allow the gate member (20) to open and close the passage (16). The detent member (30) is coupled on the main body (10) and maintained at a first position, so as for ensuring that the gate member (20) closes the passage (16), while when the detent member (30) is operated and switched to a second position, the safety is disarmed. The present invention mainly utilizes the detent member (30) to ensure the gate member (20) to close the passage (16). When the main body (10) bears the designated torque, the energy absorption area (E) allows the main body (10) to distort in response while the gate member (20) may still close the passage (16), so as to prevent the risk of decoupling and in order to meet the standard of ANSI/ASSP Z359.12-2019.
