1. A coupling element for a fluidic coupling to a terminal, the terminal having an interface with a cylindrical shell, the coupling element comprising:
a coupling body delimiting an inner conduit for a flow of fluid, the inner conduit extending along a longitudinal axis,
a valve movable in translation longitudinally with respect to the coupling body inside the inner conduit, the valve being elastically returned along a forward direction to a forward position, where the valve closes the inner conduit, in an uncoupled configuration of the coupling element,
clamping tabs,
a barrel body arranged around a first radial surface of the coupling body, the first radial surface being radially oriented along the direction opposite the longitudinal axis, the barrel body being longitudinally movable in translation with respect to the coupling body,
each clamping tab being received in a respective opening belonging to the barrel body,
each clamping tab being displaced radially in translation with respect to the barrel body, within the respective opening thereof, and with respect to the coupling body, by mechanical cooperation of the clamping tab with a tapered portion of the coupling body, centered on the longitudinal axis and oriented along a rearward direction, said radial translational movement taking place from an initial radial position of the clamping tab, in the uncoupled configuration of the coupling element, to a radial clamping position of the clamping tab, offset along the longitudinal axis along the rearward direction with respect to the initial radial position,
each clamping tab comprising a cooperating surface formed radially opposite the tapered portion and configured for mechanically cooperating with the terminal interface and thereby preventing a withdrawal of the terminal; with respect to the coupling body when the clamping tab is in the radial clamping position,
a first elastic return member, returning the barrel body along the forward direction, the barrel body abutting along the forward direction against the clamping tabs when the clamping tabs are in the radial clamping position,
means of transmission interposed between the valve and a drive element, among the barrel body and at least one of the clamping tabs, the drive element being apt to drive the valve via the means of transmission, from the forward position to a rear position, where the valve opens the inner conduit, when the clamping tabs move from the initial radial position to the radial clamping position, and
at least one port, provided through the coupling body, coupling the inner conduit to a volume surrounding the first radial surface of the coupling body, the means of transmission extending through the port or the ports when the valve is in the rear position.
