Choker collar hardware and sizing questions

[nuki]

I was curious if anyone knew the name of the hardware on this leather piece (not the shackle). I have looked everywhere and tried buying different parts to try to make them. I have seen then on expensive items and also made cheaply. The ones I have tried purchasing are held in on the other side of the leather by screws. They don't seem to have a plate that is generally seen with bag hardware. The bag hardware I did try tends to have a thickness of the loop at maybe 6mm or so and shallow as to make it sort of hard to pass anything through it. I am looking for maybe a 3mm thickness in the metal itself.. I hope yall have some ideas, this is driving me crazy.

Also does anyone have any tips for collar/cuff sizing? I would really like to start doing custom, but I have zero confidence. One of my measurements for a cuff was small and another was too large. I was taking actual measurement and adding 1/2 an inch. I am not sure which specifications to follow for leather collars. Also if anyone has tools for accurately measuring the sides of what is already made. I have a mandrel for bracelets. Not quite sure how to accurately do collars. 

Thanks!!

where did you find those images?

however, that system is really insecure.
