ABSTRACT:
A thermoplastic unitary molded seal comprises a tab, a socket depending from the tab, a pair of links extending from the tab and a locking member secured to the other end of the links. A tether is secured at one end to the locking member adjacent to one of the links and at another end adjacent to the other of the links. The tether is attached at one of its ends by a reduced cross-section to permit the tether to be severed from the locking member. The locking member comprises a pair of resiliently secured tangs attached to a cross-member in which there are a pair of recesses and a transverse hole. The recesses and hole receive the tether therethrough. The recesses and hole are inserted within the cavity of the socket with the tether free end inserted so as to lock the tether within the recesses and hole. The tether includes at least a pair of projections, one projecting from the tether on each side of the locking member so that when the tether is locked to the locking member in the socket the tether cannot be removed. The tangs include rearward facing projections which engage mating recesses in the socket. In a further embodiment, the socket has apertures at the bottom region thereof for receiving the tang tips for providing visual evidence of tampering, the tangs displacing in the socket while locked.
