My night bag tube connects to my Hollister urostomy bag with a click connection, but to put it on or take it off, I have to wiggle it. Before disconnecting, I stand up to make the liquids all go down into the night bag. I then turn off the spout, sit with a tissue under the connection, remove the connection, and raise the end of the tube to verify that all liquids have gone into the night bag. I use the tissue to daub at the urostomy pouch and put the stopper back on.
