A device for the connection of pipes of whatever section or of pipes with elements forming part of a plant such as housings or tubular bodies of whatever section provided in automatic valves or other apparatus. The device comprises a muff of a flexible material provided on its inner periphery with a tightening membrane in the shape of a lip or of a hat. The device is characterized by cooperation with the lip of guiding or centering means for the pipes to be introduced. The guiding or centering means consist of a piece (6) formed of a series of rings (7, 8, 9) of different sizes which are coaxially maintained in their respective places by cross pieces (10). The outer ring (9) of the centering piece is connected by arms or holders (11) to a fixing collar (ring) (12) which in general is introduced into a groove (13) provided in the interior of the muff.
