John, I think you need to to watch the movie RV staring Robin Williams to get some pointers about sewer connections.. LOL
You need the hose, plus you need the connection that goes into the sewer pipe. Some are threaded and some are not. On the pic you posted you need the right angle connection on the right end of the hose pic and a sewer donut as Old Coot said.
Something I use is a flush king. This hooks to your sewer outlet on the trailer and has a hose connection so you can black flush your black tank. It also,has a clear elbow that allows you to see when your water runs clear..
