This is also called a "slippery figure of eight". I would call it "almost a figure 8".
It is a quick release hitch often used by Ray Mearsduring his bushcraft television series. The hitch is known for the ease in which it can be tied even whilst wearing gloves or mittens in cold climates. This hitch is also slipped and therefore can be released by pulling the short end of the rope.
That all sounds good although I am not sure when I would like to be quickly released, but I am sure there would be such a circumstance. What do you think?
