They are used in everything from cars to washing machines, providing years of service without even a seeping of water. When I try to get one off that has been on for a few years, it is generally a fight to remove the clamp, then it's generally a no-holds-barred brawl to get the hose off the nipple. I've never seen one fail by letting go or cutting the hose in any the junkers that I've driven or been responsible for keeping up over the years. Considering that the laws of physics don't change just because the wheels leave the ground, what mechanism will make the spring clamps let go in an airplane when they don't let go in any of the other situations?
