Abstract: A fluidic connection system for connecting two two-phase pipes includes two coaxial sleeves defining a central flow flowing through the inner sleeve and an annular flow flowing through the space between the inner sleeve and the outer sleeve. The connection system includes a second complementary connector that is configured to be fastened to the end of one of the two-phase pipes and a first complementary connector that is configured to be fastened to the complementary end of the other of the two-phase pipes.
