ResMed FX mask hose clamp

I've seen similar designs on other masks to make them more comfortable I've only tried this for one night, and at this point and it made a huge difference !.

Just make sure you clamp it on the free end of the strap so it can move and not dig into your head.

Enjoy :).

Update, I found the old design a little large and clunky, so I've designed a slimline module, so far so good :).
