ABSTRACT:
A security seal of the type comprising a shackle and a locking mechanism formed of a single piece of resilient plastic and comprising a shouldered stud and a socket having resilient stud engaging means positioned on the shackle in spaced relation to each other, in which the socket comprises a relatively thin flexible wall having an aperture with means for receiving the stud in locking engagement, and a second protective wall surrounding the first wall in spaced relation thereto. The flexibility of the first wall allows a greater interference between the shoulder of the stud and the locking means of the socket, providing a greater overlap of the locking surfaces, while providing less insertion force, and the surrounding wall deters attempts to release the stud from the socket without leaving evidence of tampering.
