An improved bag seal of the type typically used to close and seal the necks of cloth or other similar bags with a flexible strap. One end of the strap is attached to a non-resilient ferrule having an elongated housing with a passage therethrough for receiving the second end of the strap. The housing is received within a bore of a sealing block and thereafter is crimped to lock the housing to and within the sealing block and the strap to and within the housing. One or more cutting edges formed on the exterior of the housing permit insertion of the housing within the bore without cutting the sealing block, but upon attempted removal of the housing, the cutting edge cuts into the sealing block to provide a visual indication of tampering. Moreover, before passing the second end of the strap through the passage in the housing, the strap is passed through a slot in a flap rotatably mounted to the sealing block near an end of the bore. With the strap through the slot, the flap is held in a rotated position along the path of movement of the housing and the bore. Upon attempted separation of the housing from the bore, the flap becomes partially or completely detached from the sealing block, thereby providing another visual indication of tampering with the seal. Identifying indicia are affixed to the seal to prevent the disassembly and subsequent reassembly of the seal with counterfeit components.
