I drilled the appropriate size hole for a wooden dowel. Added some krazy glue inside the hose to secure it to the dowel. Then just cut a hole big enough at the end of the hose that goes under your sleeve to fit a large safety pin to secure it. Careful though, make sure the hose length is appropriate.
Excellent picture of the original hose connection! This is the first time i see this feature. Looks like i'm goiong to look for some more pictures in the Supertrooper gallery now.
