Short answer: This one!

This comes with the brass fittings to fit any outdoor UK tap. It includes (all brass) 1/2", 3/4" and quick connector fittings. You will be able to leave the adapter on the outdoor tap then just use the quick connector fitting to click it on and off without having to screw anything on and off. Easy!

It will also fit any accessories you have like sprinklers, pressure washers (all types) and other hoses.
