A torque restraint device for connection to a top drive or to a travelling block of a drilling rig. The device is reversibly connectable to a guide track connected to a mast of the drilling rig. The device includes a main body supporting a pair of lockable jaws connected with a hinge body. The jaws are configured to form a closed and locked bracket for engaging the guide track and configured to pivot on the hinge body to provide an open bracket to facilitate disengagement of the device from the guide track. The hinge body forms a connection between at least one of the jaws and the main body.
