1. A female connector member, comprising:
a connector body defining a fluid passageway having an opening adapted to receive and connectable engage a male connector member;
a slot defined by grooves or walls of the connector body; and
a verification tab received in the slot and slidingly movable within the slot along the grooves or walls in a lateral direction perpendicular to an axial direction in which the male connector is insertable, the verification tab having an edge that is contoured to cause lateral movement of the verification tab from a first position in which the verification tab is concealed to a second position in which the verification tab is visibly exposed when engaged by a projecting feature of the male connector member during insertion of the male connector member into the opening, whereby effective coupling of the quick connecting coupling members can be verified;
wherein the connector body has a groove at an inner surface of a wall of the connector body adapted to receive and guide a protuberance projecting from the male connector member to prevent rotation of the male connector member relative to the connector body during connection.
