Help securing hose with Exit Bag method

[iiiinfinityyyy]

I've got my exit bag made and the tank set up and everything, but I am struggling to find a way to have the hose go into the bag. The hose I have is heavy, so it puts too much weight on the bag if I tape it in the bag directly. I tried taping it to the back of my neck, and it stayed there, but it doesn't feel as secure as I'd like. Any ideas on how to secure it to myself?

check Final Exit by Derek Humphry(should be on archive.org or elsewhere), pages from 132 to 139 explain all operations related to exit bag

Gaffer/duck tape should stick?
