If the inventor got the idea from his Turkish captors, he mutated it a lot.

There is a traditional design of Turkish wedding ring which is a bunch of linked rings. It's a puzzle to figure out how to assemble it so it fits on your finger, but a rather easy puzzle. (I used to have one, made of brass). Supposedly the idea was that if a wife took it off for an extramarital fling, she wouldn't be able to work out how to get it back on. Hmmm.
