A shackle 1 has a body 2 connected to a jaw 3 at a pivot element 4; a lever 10 is connected to the body 2 by a pivot element 6; an actuator element 9, of actuator 8, and a locking element 7 are also attached to the lever 10 so that they may both rotate and move linearly relative to it; the locking element 7 engages the body 2 and the jaw 3 in a locking configuration and slides to a release configuration where it disengages the jaw 3. Preferably, the actuator 8 is a hydraulic ram with the actuator element 9 being the piston; the lever 10 includes two slots of differing lengths 10b,10c; when in the release configuration the piston 9, engaging slot 10b, is fully extended to push the locking pin 7, engaged with slot 10c, out of the jaw 3, but still housed in the shackle body 2. Preferably, the jaw 3 has a through bore for receiving the locking pin 7, aligned with other bores in the body.
