What are they called? Are they still legal? Can you still buy them?
ISTM that, especially the screw ones, are much more forgiving on
difficult surfaces than the plastic ones with an obo(?) nail on one side.

Memory says they were called buckle clips - there's someone on eBay selling them but although googling shows there are people who claim to make them I've not seen them on sale for quite some time. I guess the extra time taken to do up the buckle made them a non-preferred method.
