A disconnectable device for making a sealed connection quickly between a smooth and rigid tube and a flexible hose which is engaged over the rigid tube, the diameter of the tube being greater than the inside diameter of the hose. A rigid ring preferably made of metal or of a semi-rigid plastic, is disposed coaxially around the hose, the ring having an inside shoulder constituting an axial abutment for the outside surface of the hose, the abutment sufficing on its own, by virtue of the wall of the hose being pinched thereagainst, to urge together the sole pair of complementary sealing surfaces of the device, one on the tube and the other on the inside surface of the hose. Complementary axial fastening means are connected respectively to the ring and to the tube.
