When/where did worm-type hose clamps first appear?

Always wondered when the modern, superior worm-style hose clamps first appeared. An auld auto/aircraft/machinist friend who was around then says during WWII. Anyone know for sure, first application(s)? The CCCA still deducts points if you use anything but the original Mickey Mouse wire clamps on '30s cars, and i believe 1940, maybe '41.
