Abstract
A tamper-proof tie includes, in one embodiment, a head and an attached strap. The head is shaped to include an elongated interior channel, an articulating locking tang, a strap limiting stop and a door activation surface. The strap includes a first end formed onto the head, a second end and a strap limiting projection disposed between the first and second ends. The portion of the strap from the first end to the strap limiting projection is in the form a flexible filament. The portion of the strap from the strap limiting projection from to the second end includes a top surface, a bottom surface, a ladder structure having a window, an anti-tampering projection formed on the top surface and a door formed on the bottom surface, the door adapted to pivot between an open position and a closed position. In use, the strap is inserted into the interior channel so the tie forms a closed loop. As the strap is inserted into the head, the locking tang engages the window to prevent withdrawal of the strap from the head, the strap limiting projection abuts against the stop to limit the minimum size of the closed loop and the door activation surface urges the door from its open position to its closed position. Together, the strap limiting projection, the anti-tampering projection and the door enclose the interior channel to protect the locking tang from tampering.
