<p>A clutch assembly (10) for releasably connecting a lifting cable to an anchor embedded in a building component (such as panel), the anchor having an anchor head lying within a recess in a surface of the component. The clutch assembly (10) comprises: a body (30) having a portion adapted to lie within the recess partially around the anchor head; a coupling (20), mounted through an aperture within the body (30) for relative pivotal movement; a locking pin (40) for releasably locking the body (30) to the anchor head; and means for releasing the locking pin (40) from a position in which the body (30) is locked to the anchor head. Various improved means for releasing are disclosed. One means for releasing is actuated by pivotal movement of the coupling (20) relative to the body (30) in a first direction followed by pivotal movement of the coupling (20) in a second direction opposite to the first direction.</p> |
