Quick-connect tube coupling

A quick-connect fitting comprising:

• a polymeric first connector,
• a polymeric second connector,
• the first connector being either a male fitting or a female fitting, and the other of the male fitting or the female fitting being the second connector,
• the female fitting having a longitudinal cylindrical cavity having therein a retaining ring retaining an o-ring,
• the male fitting having a cylindrical body and a tubular sealing element extending longitudinally therefrom positionable within the female fitting and o-ring in sealing engagement, and
• a clip pivotably connected to the second connector moving between a first position connecting the female fitting to the male fitting when the male fitting is positioned within the female fitting and a second position in which the male fitting is removable from the female fitting,
• the clip comprises
• an end wall having a tube-engaging aperture operable to engage the first connector in the first position, the end wall and the tube-engaging aperture extending beyond an end of the second connector and operable to retain the male fitting connected to the female fitting in the first position, and
• a projection transverse to the longitudinal direction of the female fitting engaging a corresponding engaging feature on the female fitting in the clip first position inhibiting relative movement between the clip and the female fitting in the longitudinal direction of the female fitting.
