It aint a complicated little spud, and certainly nothing that would get your nibblets stiff. You can actually make one by chopping a cable stop off a road bike center-pull brake, but they are, as you can see, ready-made and generally available from the spare parts bins locally.
If you find a stash of them new, then snap them up and swap them on the street. Cash money!
