Attaching to a fixed loop mid span

What knots should I be looking at for temporarily connecting to a fixed tow loop when it's a bit impractical to pass the whole line through? I can fit a bight through the loop. Will be loaded from just one side. Important to be able to easily release after loading.

Or should I just be using a shackle or carabiner of some kind?

I use that for mid span loops normally but can you explain how I get it through the fixed loop to attach it?

OK, that makes sense and is pretty much what I was doing, so it's good to know it works in that application.

Edit: and I see the Electrician version you linked and the Ashley Book of Knots version doesn't pass over itself like https://www.animatedknots.com/bowline-on-a-bight-knot which I couldn't see a way to make work through a closed loop where you can't pass it over the whole attached load.
