Quick connector with low insertion force retainer

A process for coupling a tube to a receptacle comprising:

• forming an endform on an end of the tube, the endform having a groove about the periphery of the endform and locating the endform in a cavity within the receptacle in a mounting position, the endform slidable into a latched position;
• installing a retainer having a first and a second legs in the cavity, each leg having a cross section that has a first minor axis and a second major axis;
• sliding the endform from the mounting position to the latched position causing the endform to engage the first and second legs minor axis that urge the first and second legs into a spread condition while the endform is traversing from the mounting position to the latched position, wherein in the latched position the major axis of each of the first and second legs are captured by parallel walls forming the groove when the first and second legs retract to a relaxed condition.
