ABSTRACT OF THE DISCLOSURE A safety hook having an improved stop for holding a clevis with respect to the hook to prevent accidental opening of the hook. A threaded bore extends through one arm of the clevis so that it sweeps past a crest on the hook as the hook is moved between open and closed positions. An insert having a smooth rounded head is received in the threaded bore, the insert being axially movable in the bore so as to position the head thereof in a position so as to engage with the crest of the hook to thereby restrict or prevent rotation of the hook. The insert has a tool-engaging feature on the end facing away from the rounded head to facilitate rotation thereof so as to achieve the required axial movement.
