Security seal with flag grip

This invention relates to security seals, and more particularly, to molded plastic seals with elongated shackles extending from a flag and including a locking socket at the junction of the flag and shackle for receiving and locking the shackle thereto. A flag seal comprises a thermoplastic socket, flag and shackle molded one piece. A metal locking tang element may optionally be molded into the socket. The shackle has a weakening groove. A finger gripping loop member extends about the flag both of which are flexible for receiving a finger. The gripping loop member provides enhanced finger gripping of the seal to pull on the seal to fracture the seal at the shackle weakening groove with an increased tensile load than otherwise possible.
