A material-economizing, tamper-evident seal is disclosed having dual, non-contiguous, symmetrically placed, reusable catches and a tear-off identification tag. Should seal replacement become necessary, the seal's identification tag is first torn off, and then the remainder of the seal is passed through one of the catches. A replacement seal with its own identification tag may then be engaged with both of the catches. The invention's preferred embodiment allows easy rotation of the identification tag, thus facilitating inspection of the tag's identifying mark, typically a serial number. The tag's tear-off feature is effected by the presence of an abscission bead, which may take one of several forms, as, for example, a row of perforations. Whereas some of the invention's components are preferably molded out of a resilient and relatively weak, thermoplastic material such as polypropylene, other components may with advantage be molded out of a much-stronger material, such as polycarbonate, instead.
