ABSTRACT:
A low permeability coupling device for coupling a first endpiece (3) extending a tube (2) with a second endpiece (10) carried by the wall (1) of a member to which the tube (2) is connected, in which the second endpiece (10) has two substantially coaxial walls (11, 12) defining between them a blind annular housing (13) for receiving the first endpiece (3), and a sealing element (15) extending between the inside face (11a) of the outer wall (11) of the second endpiece and the outside surface (8) of the first endpiece when it is in place in the above-mentioned housing (13).
