A quick connector coupling (310) for forming a severable connection in a fluid line comprises a connector body (312) defining a through bore (326) extending axially rearward from a male reception end (328) of said connector body (312). The connector body (312) includes locking pads (384) extending radially inward. A male member (114) extends through said male reception end (328) of the connector body (312) and into said bore (326), said male member (114) has a tubular surface (194) and an annular upset (190). The upset (190) has a diameter greater than the diameter of said tubular surface (192). A primary retainer (116) secures releasably said male member (114) within said connector body (312) and includes spaced apart legs (196) movable between a locked position and a released position in which the spacing between said legs (196) is increased. Said legs (196) are located inward of said locking pads (384) preventing said legs (196) from moving to a released position if said male member (114) is pulled axially forward.
