Pipe coupling comprising female coupling member and male coupling member

A pipe coupling comprising a male coupling member detachably connectable to a female coupling member,

• the female coupling member including a cylindrical female coupling body having a female-side passage extending from a front end opening to a rear end opening, the female coupling member further including a chuck member disposed radially outside of the cylindrical female coupling body to extend forward beyond the front end opening, the chuck member having a locking groove on an inner surface thereof,
• the chuck member being displaceable, in a longitudinal direction, between a temporarily connecting position and a connecting position which is rearward of the temporarily connecting position, the chuck member also being radially displaceable between a locking position and an unlocking position where the locking groove is displaced radially outward from the locking position,
• the male coupling member comprising a cylindrical male coupling body having a male-side passage extending from a front end opening to a rear end opening, the cylindrical male coupling body having a locking projection formed on an outer peripheral surface thereof so as to project radially outwardly, the locking projection being shaped to be lockable in the locking groove of the chuck member when in the locking position,
• wherein when the chuck member is displaced from the temporarily connecting position to the connecting position in a state where the locking projection has been locked in the locking groove of the chuck member, the male coupling body is drawn into the female-side passage of the female coupling member, and thus the male coupling member is connected to the female coupling member.
