Abstract: A one-piece high-security cable type seal-lock having a locking body (10) consisting of: A length of multi-stranded cable (50) having one cable end (51) permanently attached to locking body (10) within a through hole identified as fixed cable hole (11). A longitudinal cylindrical through hole (14) running approximately parallel to fixed cable hole (11) and having a centrally located annular recessed groove, thereby creating center expansion cavity (25). A locking pin (40) is held in place within locking body (10) and positioned approximately perpendicular to, and centrally located above, free cable end (52). When installed, locking pin (40) is forcibly pushed down until it pierces free cable end (52) thereby staking the cable in place and simultaneously creating cable bulge (53). The enlarged diameter of cable bulge (53) within center expansion cavity (25) is unable to be removed from locking body (10) via the lessor diameters of adjacent first guide hole (20) or second guide hole (22).

Abstract: A seal lock for use on the access doors of freight cars, trailer trucks and cargo containers or other applications requiring a one time use disposable locking device. In the preferred embodiment a C shaped locking body (10) having a locking mechanism within its upper leg member (14) and a blind hole within its lower leg member (16) and a locking pin (30) with its first end temporarily held in place by the locking mechanism within the upper leg member (14). The seal lock is positioned over the hasp and the locking pin is pushed with sufficient force to overcome the temporarily held position and is pushed through the aperture of the hasp until the first end of the locking pin (30) fully engages and is secured and supported by the blind hole within the lower leg member (16), while simultaneously the opposite end of the locking pin (30) permanently engages the locking mechanism within the upper leg member thereby securing the seal lock in place by means of a single engagement permanently secured locking means.
