transmission hose by pinching it shut so you don't lose alot of fuel/oil etc while removeing a fuel line for whatever reason.. The clamp criming pliers are different. But very few people ever use the crimp clamps, they usually replace them with bmw screw type hose clamps instead.. In fact when you buy the hoses from the dealer they usually ask you if you want the hose clamps also.
