Abstract: The invention relates to car seals for use on railroad freight cars, trucks, trailer trucks and the like, when it is desired to show at the point of destination whether the car has been tampered with. The seal provided by the present invention has a two piece cap and a sealing strip which engages in the two piece cap to provide the strap for overlapping the car door handle. In its preferred form the strap is formed of a strip which has an enlarged portion immediately behind its forward end which in final form provides inwardly-turned flanges to retain the forward end of the strip and the rearward end of the strip when inserted within the flanges, together with spring locking means which engage in coinciding holes in said strip to retain the same within the cap when the free end of the strip is inserted within the cap.
