A detachable coupling device with automatic closure for the transport of fluid, including two fluid transport pipes extending in a longitudinal direction and each having, at one connection end, a valve mechanism, the device also including an external tube disposed around each transport pipe and, in the coupled position, the two connection ends are configured to be relatively longitudinally displaceable between a first configuration, in which the valve mechanisms are closed, and a second configuration, in which the valve mechanisms are open, the transition from the first configuration to the second configuration being realized by a relative longitudinal movement of the two valve mechanisms close to one another.
