@halocline aren't prusik loops wonderful things!
they are nice, but what was described is not a prusik hitch, its a girth hitch. closely related, but different uses. if you're not into climbing, the names tend to be used interchangeably, with 'prusik' just meaning any knot used to hitch a loop of something (or the loop itself) to something else, and 'girth' resulting in childish giggles.
personally, i use a clove hitch to hitch a loop of shock cord the bolt snap, 'hitch' to the hose via a double fisherman / double double overhand, lock everything down with zip ties, and finally stow the bolt snap over the regulator adjustment knob. that way if its clipped off and you NEED IT, you can just give it a quick pull and it has enough give to reach your mouth. seems to also lay a bit nicer then when suspended from the hose.
saw that method on here a while back, cant find the original post off hand thought. completely not DIR, this is not legal advice, and your mileage may vary.
