"The general design of the cushion clips has a few stress points that are hard on the plastic.
Mine broke just slightly down the side from the top where it 'bends' to go toward the bridge of the nose. I am guessing a lot of stress is handled there.
I did try repairing my old clip, but did not find the right solvent to weld this kind of plastic. "Model airplane glue" and a 5-minute epoxy did not work.
In any case, the new clip made me able to sleep without the cushion comming off when I roll over. My sleep, and my wife's sanity thank you for the prompt service."

"I have had a CPCP for a little more than two years. In that time I have had 4 or 5 clips break. They are far too brittle for their intended purpose. For what they cost, they should be of fro higher quality plastic."
"Unfortunately these clip break to easily. I have to use about three (3) clips over the lifetime of one nose cushion."

"This part of the mask, unavoidably, is fragile and over time cracks, making the cushion fit loosely over the mouth. It is good to be able to replace just this part, as it is less expensive than replacing the whole mask."
