A connection device for making a tight connection between two ends of tubes is provided. The connection device includes a body having two symmetrical and opposite portions for engaging ends of respective tubes, and each of the portions has a hooking element to keep the tube in the connection, and a sealing element for the connection. The hooking element of each portion includes: a truncated chamber arranged in each portion; a longitudinal rib projecting into the truncated chamber; and a split ring whose ends are located on either side of the longitudinal rib. The ring is provided with an internal threading, so as to cause a blocking of the tube by any traction on the tube in a direction opposite to its direction of engagement. The ring is placed free in the truncated chamber, on one hand, and is elastically deformable, on the other. The inner diameter of the ring is smaller than the outer diameter of the tube in an unstressed or deformed state, so as to deform elastically and to grip the tube upon introduction of the tube.
