Avoid replacing expensive F20 bipap mask clips, by using cheap 20mm wide nylon plastic buckle clips, and 8 zip ties! The fix is as simple as the picture! Use 4 zip ties on each side! 3 zip ties go through the 20mm, (2cm) nylon buckle clip slot, and 1 zip tie holds it to the mask! The magnet on the mask acts as a stopper
