Abstract
Pockets, defined by molded plastic shells, are embedded in a massive concrete article. Lifting cables have rods to fit into the pockets. The shells which define these pockets are injection-molded to provide a lateral spline to pass a key formed on the lifting rod, and also have a parti-cylindrical end housing, closed by a snap-fitted cover plate, within which housing the key rotates to lock the rod in the socket when lift is applied to the rod.
