ABSTRACT:
A quick connector coupling for a fluid line includes a hollow female connector body defining an interior radial bearing surface. A male member has a radially enlarged upset and is insertable into the connector body to a first position and withdrawable from the first position to a second position within the connector body. A retainer is disposed in the connector body and has retention beams extending between the upset and the bearing surface to secure the retainer and the male member in the connector body. A ring-shaped indicator member is detachably secured to one end of the connector body. Withdrawal of the male member from the first position to the second position causes detachment of the indicator member from the connector body and signals a proper coupling.
