Careful there.
It might be specific to the aircraft you fly on, or the airline you work for.
I can tell you for a fact that the airlines we do maintenance for, none of them are as you describe. The A300's, A319/320/321's, 757/767's that I have worked on all have tubes that are murder to disconnect. You either pull the tube with such force that after a few of them your fingertips are sore, cut them, or apply heat to stretch the plastic. I always groan when I am tasked with changing them due to discoloration, damage, or life-ex.
