last night, the Velcro came detached, and I fumbled around finding new headgear. finding a backup headgear. (did not wat to turn on the lights, wife was asleep)
I have tries sewing on replacement pieces, the double stick tape ones..... all with no real satisfaction.
SO... and easy solution, with a side benefit.
I picked up some of the cable straps that are double sided Velcro, and have a slot cut in the end, so you can make a loop. These worked out great.
I pulled the strap through the slot for the loop, and folded it over. It then stuck to the hook side. Then I cut it off so it was not to long. The extra makes a nice way to attach the hose at the top. By using 2 in an X shape, it stays in the middle and not off to one side.
a picture of how it is attached:

and how the hose is held.

I hope that it holds up. If not, I will stitch it in place, but it is better than my previous attempts.
Actually, I have some snaps for another project, I may use a make snap, that is a post and a snap. It would join them. (not using the snap at all, it is just a way to fix the 2 pieces together.
edited to small pictures, sorry I did do a preview.
