Abstract

A tamper-evident, single use, ring assembly, is assembled from first and second interengaging broken rings (). The first broken ring () is of a first material and the second broken ring () is of a second material. A break in the ring of the first material is offset circumferentially from a break in the ring of the second material. The assembly of the rings forms a closed ring assembly which can be cut through in the region of the break in the ring of the first material to open the ring assembly. At least one of the rings () of the ring assembly is resiliently stressed in its assembled state such that, upon cutting through of the ring assembly, the confronting ends of the assembly move apart.
