ABSTRACT:
A security seal of the type having a housing with an opening to receive a flat strap type of shackle, in which the shackle has an aperture near the end, and said housing has internal means for engaging the shackle to prevent removal after the shackle is properly inserted. The internal means comprises deformable legs which are so deformed by the insertion of the strap end that a free end of one locking leg is caused to move through the aperture of the inserted strap to lock it against removal. In one embodiment of the invention the locking leg has hook means on the free end engaging a stationary portion of the internal structure after it has passed through the strap opening. In another embodiment of the invention two sets of deformable legs are provided so that both ends of a shackle may be engaged in the housing, thereby allowing the user of the seal to provide his own shackles with his own numbering system.
