ABSTRACT:
A padlock-type security seal having tamper-indicating means to cause the shackle ends to break through and protrude from the walls of the seal body when serious attempts are made to remove the shackle. The seal includes a pair of slots each having a shoulder for engaging the shackle ends. When serious attempts are made to force the shackle from the seal, a ramp will engage the shackle ends and force them against the seal walls. With sufficient force applied to the shackle, the shackle ends will rupture the seal body.
