Abstract
A tamperproof shackle seal, of the kind including a plug, at one end of a strap, which is self-locking within a socket at the other end of the strap, is capable of use immediately after being integrally moulded in a plastics material, without the need for subsequent manufacturing operations, by virtue of forming a recess set in the wall of the socket into which a barb projecting laterally outwards from the plug is snapped, during use, the plug being formed throughout its length to be of substantially similar transverse cross-section to the socket, and there preferably being a tortuous path presented by ribs/grooves on the plug interengaging with grooves/ribs of complementary shape on the socket, thereby hampering any attempts to release the seal without causing visible damage.
