Oh yeah, I put that there on purpose. There is still another 2 zip ties on the barb itself. That one that is off the barb is there, because the tube is pushing Up on the barb, and without the extra tie, it would no get a good seal on the barb. That pic is deceiving. I should loosen it off though, as it is a little tigher than I need. Thanks for noticing though!
You can see what I mean if you look closely to this one..
