I'm not sure what the little metal piece is called - meaning the actual found part. But in the Star Wars universe and Fett world, it is simply known as the "Borden Connector". A couple of differnet vendors offer this piece, one of which is the well known US based vendor called Machine Craft Replicas.

Another one is a Canadian based vendor on Etsy, called QuestDesignCanada.

I'm sure there are others out there, but these two vendors for me anyways are always top of mind if I'm looking for metal Fett parts.
