Quick connects and Male connects

I just got my first water fed pole and you have to attach the hose from the pole to the hose on the brush with the male quick connects.

My questions are, is there a trick to getting the hose onto it or do you just have to muscle the hose onto the male barb?

What do you do when you want to put a different brush on your pole as it seems like the hose is not going to come off the male barb connector?

The only thing I could think of is to put a quick connect or something at the top of the pole hose for switching out brushes?

A quick connect would work, but it’d add weight to the top of your pole.

I work with the pole hose wrapped externally around the pole, and a hose for each brush. Swap the brush & hose together,…
