I prefer my hose to hang above my head but don't have special equipment for it. Instead at home and at hotels I use a large binder clip with a small rope (such as a shoe lace). A large binder clip can usually attach to the headboard or to the frame of the picture above it. I tie the rope around one of the silver handles and leave a huge loop for the hose to be able to move through freely. It's not an elegant design, but it works fine for me and is easy to keep in my cpap bag.
