What kind of clip/pin is this?!

[docsfarm]

Can someone help me identify this? I have pins on my grapple that have these clips holding them in place. I need two new ones. But I don't know what to even search for. Local Tractor supply store doesn't have them.
Thanks!!

I personally don't like them; they seem to be the easiest clip to get snagged and lost. I'd almost go for a spiral clip unless you need to remove the pin frequently.
