Abstract
A quick coupling connector for removably connecting pipes, including a male member which is selectively connected within a female member to open a resiliently biased valve mounted within the female member. A safety ring is mounted about the female member and incorporates claws to axially retain the male member in a position intermediate a fully seated position within the female member and a fully released position after a first axial movement of a bush, which encloses both the male and female members, in a first direction opens a locking ring which also incorporates claws which are engageable with the male member and which normally secures the male member within the female member. In the intermediate position, a pipe associated with the male member is allowed to decompress after which the bush is moved in a second direction opposite the first direction, thereby releasing the claws of the safety ring and resulting in the release of the male member.
