the same fluid density connector and method of assembling

It is an object of the present invention to prevent damage to a rubber stopper, resulting from the encounter with a terminal fitting. A retainer 40, a more resilient stopper 60 and a pressing member 70 for the resilient stoppers are mounted in a housing 10th The retainer 40 is movable between a partial locking position and a full locking position and the pressing member 70 for the resilient stopper is movable between an initial position and a pushed-in position. The press member 70 for the resilient stopper is formed with arm sections 74, projecting therefrom. The retainer 40 is formed with Entriegelverbindungsabschnitten 46 to connect a movement of the retainer 40 from the full locking position in the partial locking position and a movement of the pressing member 70 for the resilient plug from the pushed-in position to the initial position with each other by the arm portions 24 is in sliding contact come.
