723: Travelers portable security lock for motel/hotel doors.
The tab on the large flat piece goes into the door frame latch and the
pin (it's spring loaded) then goes into the appropriate hole in the
serrated groove to hold the door closed.
725: Adjustable nipple clamp - it's missing the rubber pads. Usually
seen in pairs. Don't ask me how I know. <blush>

I've seen those film tongs, but never with that locking lever. I was

whoever came up with "nipple ring (without the rubber pads)" kinda

clamp that a bunch of people found useful for various things, and
so, since they were selling, they made more. :-)
I think it was adapted for a USAAF use in WWII. I think the Air Force
bought them, had them engraved to discourage theft for household
purposes, then issued them in large numbers.
I wonder how oxygen was distributed in a bomber. If a line were torn,
everybody dependent on that tank could soon pass out unless a crewman
had a locking clamp in his pocket.
It may have been issued to ground crews to pinch a tube during maintenance.
