I use the ones in your picture, but not for quick disconnects. I think
they are not really suitable for repeatable connections and they are
sometimes difficult to let go.

I have a static tube connector in the instrument panel with a blocked
piece of tubing in it. If I pull it out, I have static pressure from
the cockpit (in parallel to the static port in the wing). This works
very well. In fact, it works so well that I hardly see any difference
if I take the blockage out. (And yes, my static port system is leak
free). Unless I open one of the big vents in the door windows, then
the static pressure goes way off. But of course cockpit pressure is
very dependant on how tight your doors are, how much air leaks around
the throttle, etc. In my case it just happens that the cockpit
pressure is very neutral.
