The quick-fit coupling consists of female (A) and male (B) components that join together, the female component having a lock for the male one including three teeth (54, 55, 56) set in different positions along the component to engage with a shoulder on the male component. The coupling has an aperture that connects the downstream pipe (C2) to the outside atmosphere when the shoulder on the male component is against the intermediate tooth (54), the aperture being in the female component downstream of a valve. When the shoulder on the male component is against the innermost tooth (53) the aperture is closed. |
