  • Tamper-evident fastening assembly
    Patent number: 6227399
    Abstract: A tamper-evident fastening assembly for an outlet of a conduit, including a closure member for covering the outlet of the conduit, a strap extending from the closure member, and first and second fasteners connected to the closure member. The first fastener secures a first portion of the strap to the conduit by forming a first loop. The second fastener secures a second portion of the strap to the closure member by forming a second loop. Removal of the closure member from the outlet breaks the second loop but leaves the first loop intact on the conduit.
