Abstract

Apparatus for sealing a postage meter is disclosed. The sealing apparatus includes a cover with a cut-out portion. The cover portion includes two cover tab receiving openings which are positioned diametrically across from each other. The center of the cut-out portion has a bore hole that runs completely through the thickness of the cover. An insert is provided which is adapted to fit into and mate with the bore hole. The insert contains an opening which will accept a screw and also contains upwardly extending tabs. A screw is used to fasten the sealing apparatus to the postage meter. When the tabs are stacked over the screw, it is impossible to remove the screw without first breaking off the tabs. A broken tab will thus indicate that the meter has been tampered with.
