| Abstract: Seals have a flexible wire that can be looped through a hasp-like device.
The seals include a body having a recess, a plug insertable into the
recess and a snap ring for fastening the plug to the body. The plug
and/or body can have access holes for inserting the wire into the recess.
"Teeth" on the outer diameter and through-holes through the thickness of
the snap ring allow for passing the ends of the flexible wire from the
recess through the snap ring. The ends of the wire can be folded back
over the snap ring and into engagement with the teeth. Assembly of the
seal causes the ends of the wire to be securely fastened between the
teeth of the snap ring and the sidewall of the recess. Seals can include
a plug and/or body made of a frangible material such as glass, ceramic,
glass-ceramic or brittle polymer. |
