ABSTRACT:
A locking seal for use on doors of freight cars, trailer trucks and other large doors to prevent casual pilferage by non-professional thieves. In a first embodiment a length of steel cable is provided with means on each end for locking engagement with each other. In a second embodiment of the invention, a length of steel cable is provided with a stop on one end and the other end is provided with an assembly comprising a locking cap and means secured to the cable for receiving the locking cap in non-removable engagement. The locking means of either embodiment is adapted for rapid assembly without the use of special tools, yet the design of the two locking portions thereof gives the assembly a strength of engagement which is greater than the strength of the steel cable connecting the portions. The male portion of the locking means, when assembled, is completely enclosed within the female portion to protect the attachment of the cable to the male portion from physical damage. In the first embodiment, sufficient length of cable is provided between the two portions to provide a relatively large loop when the parts are assembled so that an attempt to break the seal by twisting the cable is sufficiently time-consuming as to hamper and discourage pilferage by non-professional thieves such as juveniles. In the second embodiment, the length of cable between the stop at one end and the locking assembly at the other is sufficient to enable the seal to be assembled through an article to be sealed, with sufficient excess length to make rupture of the seal by the use of pry-bars, hammers, or the like difficult or impossible.
