Sure. That's an alligator clip, Dutchware sells them, including with a slot you could probably run shock cord through: https://dutchwaregear.com/product/pl...lligator-clip/

It's kind of tempting to make a double-ended length of shock cord with clips on both ends, and use that to hold the UQ to the hammock. Surely there is a reason most UQs don't use something like this? Seems great but I must be overlooking something. I'm unimpressed with the quilt hooks on the sides of hammocks that i've used.
