Abstract: An approximately cylindrical housing is coupled to one pipe, and the other pipe having an annular protruding portion on an outer periphery at an end portion is inserted into the housing to be coupled. Inside the housing, are installed a stopper that is held at an initial position in close proximity to an opening portion of the housing and moves to a push-in position away from the opening portion of the housing when the other pipe is fully introduced inside, and a retainer having a locking piece that is inserted through an opening portion, formed in a top wall of the housing, in a direction perpendicular to the axial direction of the housing and engages with the annular protruding portion of the other pipe while the end portion of the other pipe is fully inserted. The retainer cannot be inserted unless the stopper moves to the push-in position.
