Quick obturation coupling connection

A quick obturation fluidic connection comprising

• a male connector and a female connector configured to fit into one another, the male connector and the female connector each comprising
• an inner fluid passageway extending along a main axis and
• a valve that is axially displaceable in the inner fluid passageway against an elastic return member, the valve comprising a body including a portion of widened section forming an obturation head and a proximal free end for junction with the valve of another connector, wherein
• the valve of the male connector and the valve of the female connector are configured to interact with one another by mutually pushing one another into a fluidically open position in a coupling configuration of the male connector and the female connector,
• the valve of the male connector and the valve of the female connector are each configured to be elastically returned to a sealed obturation position of the passageway by the respective obturation heads in a configuration in which the valve of the male connector and the valve of the female connector are uncoupled,
• the body of the valve of one of the male connector and the female connector comprises a connecting segment extending from the obturation head of the valve of the one of the male connector and the female connector to a proximal free end of the valve of the one of the male connector and the female connector,
• the connecting segment comprises a portion that is convergent in the direction of a neck and a portion that is divergent up to the proximal free end to define a widened end surface,
• the obturation head of the valve of the other of the male connector and the female connector is truncated at a proximal free end of the other of the male connector and the female connector to define a widened end joining surface,
• the widened end surface of the valve of one of the male connector and the female connector includes a cavity, and
• the widened end surface of the valve of the other of the male connector and the female connector is in the shape of a domed vertex shaped to match a shape of the cavity, so that in the coupling configuration, the widened end surface of the male connector and the widened end surface of the female connector join each other through the domed vertex and the cavity to form a substantially symmetrical member of revolution around a main axis, the symmetrical member having a longitudinal section which varies according to a curvilinear and progressive longitudinal profile.
