you're not trying to fit it in correctly - IIRC the best thing (IF you're going to do this) is to use two per hose, push the hose up a bit and wrap 1 zip tie around the top and 1 through the hole - sort "figure 8" them together... it'll hold things in place, allow a little give and be easy to snip off when you're done
