I attach my guylines to the tie outs with a bowline knot. But I make the loop pretty large and slip the tip of my trekking pole into the extra loop. The same could be done with a carabiner or S-hook as described above if you want to be able to quickly remove the lines for whatever reason. I found tying hitches around the pole a pain, they always slipped on me while I was setting the tarp up. They're great under tension, not so much before that.
