ABSTRACT:
A one-piece injection molded tamperproof security seal is used for sealing the ends of tubular members, such as are found in some types of electricity meters. The seal is compact, it may be applied where there is limited space, and it has a high degree of inviolability. The seal comprises a plug adapted to be received in the tubular end, blocking means on the plug adapted for cooperation with engagement means on the tubular member, first locking means on the plug, and a closure portion which is hingeably attached to the plug and provided with second locking means. The seal has an open configuration in which the closure portion is remote from the plug portion and a sealed configuration in which the closure portion is folded over the plug with the first and second locking means in mutual locking cooperation. In the sealed configuration, the plug is within the end of the tubular member to be sealed, and displacement means on the closure portion cooperate with the plug to displace the blocking means from an unblocked configuration to a blocked configuration at which the blocking means cooperates with the engagement means on the tubular member.
