Abstract
A tube for transporting a fluid is provided integrally with a quick connector on a tube end portion. The quick connector has a tubular connector housing defined by the tube end portion in a form of diametrically enlarged shape, an O-ring contacting with an outer peripheral surface of a mating pipe to provide a seal, and a retainer portion. The retainer portion has a retainer tubular portion defined by a leading end portion of the connector housing and an engaging recessed portion. The engaging recessed portion allows an engaging projection of the mating pipe to fit in the engaging recessed portion resiliently or under a resilient force from an inner side toward a radially outward direction in a mutually engaging relation.
