ABSTRACT:
A lug attachment for detecting the removal of a wheel comprising a frangible shroud and an internally threaded member for attaching said shroud to the lug of a wheel mounting plate. The threaded member comprises a pair of split sleeve sections that laterally flex for engagement with the threads of a lug by an axial thrust. Thereafter, an axial thrust of said shroud clamps and secures the threaded member onto the lugs. Means formed on said shroud retains the threaded member in its axial position of attachment to a lug and prevents removal except by breakage.
