ABSTRACT:
A seal and lock includes a flexible metal cable held permanently at one end in a housing, the other end being insertable through the housing and is locked therein by a spring-biased ball which wedges against the cable upon an attempt to pull the cable from the housing. A second ball is located between the spring and the first-mentioned ball, and wedges against the cable to further prevent removal thereof and to prevent twisting of the cable as a way of removing the cable from the housing. The second ball is of sufficiently soft material so that the cable when pulled digs into the second ball to increase the jamming force against the cable.
