Cuff (with Quick Disconnect) - threads onto the tool end of your 1 1/2"
(36mm) hose. For swivel use and quick disconnect of curved hand
tube. Alto uses a "squeeze type" Swivel End Cuff (with
disconnect) on some of its models. The newer part (#302001345)
requires more hand strength to release the end tube. I prefer the
style featured here with the thumb-release.
