ABSTRACT:
A ball seal having an elongated, flexible metal strap for providing locking engagement with a ball-shaped housing. A locking platform, having two frangibly joined leaves, is mounted in the housing for receiving the ends of the metal strap. A pair of locking tabs are located on one leaf and a pair of locking rings are mounted on the locking platform. The seal is placed in use by passing the strap through a structure to be sealed and then sliding the ends into the locking platform to effect locking engagement between the strap ends, and the locking tabs and rings. If the strap is forced from the housing, the leaf having the locking tabs thereon will be torn from the other leaf at the frangible joint, thereby destroying the locking platform beyond reasonable repair.
