Abstract

A shackle comprises a shackle body and a shackle jaw, the shackle jaw connected to the shackle body by a pivot element about which the shackle jaw and shackle body may pivot relative to one another. The shackle further comprises an actuator element and an actuator and a locking element, the locking element arranged to engage the shackle body and the shackle jaw in a locking configuration and to disengage from the shackle jaw in a release configuration. The locking element is slidable along its longitudinal axis between the locking and release configurations and the actuator element is arranged to slide along its longitudinal axes. The pivot element, the actuator element and the locking element are connected to one another by a lever that is pivotally attached at one end to the shackle body and wherein the connection between the lever and the locking element and the actuator element permits pivotal movement and limited linear movement between the lever and the locking and actuator elements.
