Abstract: A quick connector coupling comprises a collar port having a passage and a collar, a connector to be coupled to the collar port and comprising a tube portion to be received in the passage, a flange on the tube portion, a sealing ring received in a groove on the tube portion, and a locking clip for engaging the collar and an engagement surface of the connector to lock the connector against axial movement. With the connector in a mounted state, the flange has extensions extending along the tube portion beyond the collar, the extensions carry a terminal ring with a surface facing the flange forming the engagement surface spaced from the collar, the clip arranged to lock the connector on the collar port against axial movement, and the groove is axially formed on the tube portion such that the groove is closer to the flange than the engagement surface.
