nursie: When I originally connected them I couldn't even get them onto the conenctors, so I lubed the connectors with vaseline... then applied the clamps when the hose was in place. When removing, I wedged the clamps open, but still couldn't pull the hoses off the connectors. But I was looking to cut the hoses down so I cut them and then just hacked the 3-4" left on the connectors apart with a knife.
