A quick connector for making a severable connection in a fluid line comprising: a connector body defining a through bore extending from a male member reception end to a tube connection end along a longitudinal axis, the through bore sized to receive a male member generally having a tubular shape sized to extend into the male member reception end, the male member having an annular bead, the annular bead having a diameter greater than a diameter of a tubular outer surface of the male member, the connector body having a bead checker, wherein the connector body engages with a retainer (213, 213') for securing the male member to the connector body in the assembled configuration, and a lock cover releasably securing the male member within the connector body and including a verifier, the lock cover moving between a latched position and an unlatched position, wherein the verifier has a verifier body that is extended from an internal surface of the lock cover, wherein the bead checker is sized and positioned to be laterally moved outwardly from the longitudinal axis by the annular bead of the male member and the verifier body allows the lock cover to move to the latched position only if the verifier body is not contacted to the bead checker of the connector body or the annular bead of the male member, the retainer (213, 213') has a pair of retainer tabs (214, 214') and each of the retainer tabs (214, 214') comprises an angled guide surface (216, 216') that is configured for allowing the retainer tabs (214, 214') to be resiliently pushed away from the longitudinal axis of the through bore by contacting with the annular bead of the male member when the male member is inserted into the through bore of the connector body in the assembled configuration, characterized in that the bead checker of the connector body is integrally formed with the connector body. a connector body defining a through bore extending from a male member reception end to a tube connection end along a longitudinal axis, the through bore sized to receive a male member generally having a tubular shape sized to extend into the male member reception end, the male member having an annular bead, the annular bead having a diameter greater than a diameter of a tubular outer surface of the male member, the connector body having a bead checker, wherein the connector body engages with a retainer (213, 213') for securing the male member to the connector body in the assembled configuration, and a lock cover releasably securing the male member within the connector body and including a verifier, the lock cover moving between a latched position and an unlatched position, wherein the verifier has a verifier body that is extended from an internal surface of the lock cover, wherein the bead checker is sized and positioned to be laterally moved outwardly from the longitudinal axis by the annular bead of the male member and the verifier body allows the lock cover to move to the latched position only if the verifier body is not contacted to the bead checker of the connector body or the annular bead of the male member, the retainer (213, 213') has a pair of retainer tabs (214, 214') and each of the retainer tabs (214, 214') comprises an angled guide surface (216, 216') that is configured for allowing the retainer tabs (214, 214') to be resiliently pushed away from the longitudinal axis of the through bore by contacting with the annular bead of the male member when the male member is inserted into the through bore of the connector body in the assembled configuration, characterized in that the bead checker of the connector body is integrally formed with the connector body.
