I just gotta figure out how to make one out of better materials.
A fairly straight forward option could be bending spring steel or music wire of a suitable dimension? (If that is not exclusive, springy or corrosion resistant enough you might have a look materials like nitinol, phosphor bronze or beryllium bronze with a suitable heat treat after shaping).
Lol, I tried using a small section from a wire hanger and I’m already getting frustrated
Try a local fishing shop. They usually have things like you made. Speed clips, fast locks etc.
You just blew my mind sir! I bet there’s something in my tackle box I can use. If not, it’s a good excuse to go to the local Bass Pro!
