ABSTRACT:
Tamperproof shackle seals formed as one-piece plastics mouldings and including, inter alia, the following features: a plug portion of non-circular outline for co-operation with a mating countersunk portion of the socket mouth to prevent effective insertion of a blade; a stop formed on the strap near the plug to limit the effective length of the strap when used with a padlock hasp; respective webs extending along the lengths of resilient fingers in the socket and connecting them either to the adjacent socket wall, or to those fingers disposed adjacently thereto on either side; to prevent free movement of the resilient fingers; and a filler for the plastics material which presents a barrier to heat re-sealing after tampering.
