These buckles do exist and are called repair buckles. I have used them to fix nylon halters that don't come apart. This picture is from the Harness Hardware catalog (Ontario, Canada).

Yes, that's totally fine with me that you posted the picture. Thanks for your interest!

Hi there. As far as I know the Rodeo letter set is not being manufactured anymore, so I've designed it as a 3D printed set. It's obviously not as strong as metal, but with a press I get really good results, as well as many others who have got a set from me. I make them in 1/2", 3/4" and 1" size, including numbers and the "&" symbol, as well as a guide for lining them up and now even a tray to store them in. If you're interested, you can have a look at my listing in my Etsy shop. My shop name is SaddleHillsLeather. Not sure if I can add a link here, but I'll try: https://www.etsy.com/listing/976551503

I'm looking for the same part as wendlynne. Did you ever find one? And Uwe, did you get your parts sorted and come across any in there?
