Hardware suggestions, please

My short research yielded no results for me. I have a battle rope that I'd like to try and climb, even though it's not quite designed for that purpose. I'd like to secure it to a tree limb. Looking for suggestions, I'd like to be able to take it down so it's not so exposed to the elements. All I can think of is securing a chain around the limb, fairly snug, but before I do that slide the rope through a couple of feet and make a knot. The knot will prevent the rope from slipping out. Now, what does someone with some experience have to offer. If it's additional hardware, please leave names / links. Much appreciated.
