I put a little diamond knot on each tieout point and I remove the tarp lines every time. The video below is about my ridgeline but I have just one of those "diamond rings" at each attach point and all my tarp lines have an eye spliced into the end, so I just slip the loop over the diamond knot and cinch it up a bit and I'm good to go, easy on, easy off, but it never comes off uncommanded.
