Abstract
A pipe coupling includes a male coupling member detachably connected to a female coupling member by a chuck member of the female coupling member. The chuck member is disposed radially outside of a female coupling body to extend forward beyond a front end opening. The chuck member is displaceable in a longitudinal direction and also radially displaceable between a locking position where a locking groove locks a locking projection and an unlocking position where the locking groove is displaced radially outward from the locking position to unlock the locking projection. When the chuck member is displaced rearward from a temporarily connecting position to a connecting position in a state where the locking groove has locked the locking projection in the temporarily connecting position, the chuck member draws the male coupling member into a female-side passage to connect the male coupling member to the female coupling member.
