A lifting hook safety lock comprises a central element so shaped that when inserted into the circular portion of a lifting hook it cannot rotate out of the locked position. The shaped central element is accompanied by two side plates one to each side held in place by fixing bolts. The central element may provide a suitable space to accommodate for example a shackle. It may also be impossible for the central element to exit a lifting hook at the throat opening.
