Tamper-proof or check seal for e.g. merchandise protection, has locking ring that locks by its central part deformation and by return of retaining units in notches of tie wire, where wire and ring have edges with specific blocking angle

摘要

The seal has an elongated locking ring (2) whose central part alone is deformable, and a tie wire (3) to be introduced without gap in a central passage (23). The locking is obtained by deformation of the central part, then by return of retaining units in notches (8) of the wire. The wire and the ring (2) with a central ring (4) have edges that have a blocking angle of 90 degrees to lock the seal.
