ABSTRACT:
A seal for a projecting drum ring includes a housing which is open at the back and the bottom and has a stem with a tapered head extending downwardly, the stem being connected by a relatively weak joint to the upper wall of the housing, the upper wall having a strap extending therefrom in order that when the tapered head is pressed through the ring it is retained against undetected tampering but the seal may be easily removed by pulling on the strap thereby breaking the stem at the connection to the head.
