1/2″ Looploc. Do they exist?

I am not sure what you mean by a "looploc". Could you post a picture or a diagram?

These would be too big. May not be the right item.

Here is what I'm looking for

I haven't seen those in 1/2" but have seen thicker ones for holding loose strap ends next to the loaded strap. They didn't appear very strong – You may have luck in finding them made of metal. Depending on the purpose you want them for you could try a ring or D. You could get 1/2" triglides and cut one end off.

I had the same issue with a recent MYOG project and found them on Etsy…check these out…

I've bought about a hundred from http://www.plastic-buckle.com/rings-loops.aspx. I've bought a bunch of other stuff from them. I recommend them.
