Odd handcuff

Can anyone tell me about this please

I think but I’m not sure that they are of German origin. Are there no markings on them?

It looks like a Heinkel nipper, patented 12 Oct 1964. This is the link to the patent document:

No markings. Any idea on price. I’ve had them for 25 plus years
