Abstract
A tamper-proof tie includes a head and an attached strap. The head includes a strap accepting channel and a blind cavity. The strap accepting channel includes a strap entry end and a strap exit end. The blind cavity includes an open end. The head includes a flexible locking member comprising first and second ends which are fixed in place within the head. The strap includes an anti-tampering device which comprises a finger and a projection. In use, the strap is inserted into the strap accepting channel so the tie forms a closed loop. As the strap is inserted into the head, the locking member engages the anti-tampering device to prevent withdrawal of the strap from the head. With the tie formed into a closed loop, the anti-tampering device substantially encloses the entry end and the exit end of the strap accepting channel and the open end of the blind cavity.
