(57) The manifold (1) comprises a flange (2) and a tube-like elastic part (4) made of elastomeric material, which are connected to one another without using adhesives. The function of mechanical connection of the two components (2, 4) is separate from the function of gas and liquid tightness. The flange (2) and the tube-like elastic part (4) are provided with complementary formations (5, 6) defining a first step-like part (7a, 7b) which ensures stable connection between the two components (2, 4) in conditions of mutual clamping. The same complementary formations then define together a second step-like part (8a, 8b) which confers the necessary preloading on a seal lip (10) of the tube-like part (4) of the manifold. A further step (11) ensures connection of the two components (2, 4) during storage and handing of the manifold.
