Abstract:
This pipe joint comprises: a housing; a retainer movable from a standby position to a lock position; a detection arm that is provided on the retainer, restricts pushing of the retainer into the housing by a restriction wall of the housing when the detection arm is in the standby position, and removes the restriction by the restriction wall when the detection arm is bent radially outward of the housing; a pipe lock arm that is provided on a rear side relative to the detection arm, and faces a spool of an inserted pipe on the rear side when the retainer is in the lock position; and a detection claw comprising an inclined surface that is mounted on the detection arm so as to be inclined with respect to a pipe insertion direction, and converts a pushing force received from the spool into a radially outward force, and a parallel surface that is mounted on the detection arm so as to be parallel to the pipe insertion direction on a radially inner side of the inclined surface. The thickness of an inclined surface portion is 20% to 90% inclusive of the thickness of the detection claw.
