Good evening, Once received, I go to the basement dismantle the old garden hose which (I confess!) I had broken by dropping which allowed to put spray quality. (Photo 2) I disassembled, unscrewed ... I also unscrew the blue cap which in my case is not helpful and provided me with the tip screwed in the package on my cock. Hop! ON CLIPSE then the hose and long hose (much more convenient than the old because of its entanglement cut me off the water supply very often when I was watering the garden! AND HOP! Topiary watered! PERFECT! Easy storage! EFFECTIVE!
