Variation on belt buckles question

I am trying to find the manufacturer of a certain kind of buckle. The
bail has teeth and attaches to the belt much like those on army web
belts. It has a normal peg for going in the hole.

I could make one but am not sure if it is patented or not. I like it
because I could make an opening in the frame for enamel. Besides you
can just remove the buckle and not have to take off the belt at
security checkpoints.
