Those are the same quick disconnects I use. I probably use too many.
The catheter gets an open flow. A short extension hose puts me at a closed flow that mates to a closed flow in the suit. The closed flow prevents the plumbing from draining and making a mess when disconnected. You might spill a drop or two with the closed flow as you disconnect.
But the big key one is being able to disconnect the extension hose from yourself. You don't ever want to be in the position where you need an adaptor or take the condom off in order to take a pee.
I prep before laving home/hotel. Always test fire the plumbing to make sure everything is comfortable. The ability to stop and take a leak before suiting up is a fairly normal experience. No special tools needed.
The sockets are always the shrouded release buttons. I want that ridge around the button to prevent accidental button pressing. The original supplier, which I once bought directly through but won't anymore.

McMaster also carries the noroprene hose. (not neoprene)
Another tip, getting that damn thing off. The inverted peel isn't the best. I have found that the stretch to insane diameter and pull the adhesive perpendicular releases it better. Still not fun or enjoyable. But that stretching thins out the adhesive so it isn't as bad. And clean up, WD40. Surprisingly mild on skin and just enough solvent to remove the glue. Generally do this a day after diving when you see the lint stuck to the glue. You know just the areas to clean. And when done, washes off in the shower with soapy water (the glue won't wash off on its own).
And if you are tugging at hairs, you didn't manscape enough. It will grow back, don't worry about it. You will learn how much or little is needed in time. Part of that learning curve.
