I also saw that it was just a slip connection and put a hose clamp on it. Soon after, I was dumping and noticed that when I turned on the macerator pump the hose started to get longer. I shut the pump off and realized that I had forgot to take the cap off the plastic end piece and the pressure was making the hose grow. Good thing for the clamp or there would have been a mess. Needless to say, I now remember to take the cap off.
