Abstract: An apparatus for the gasification or aeration of liquids. Elongated aeration elements are connected to a distribution conduit and have an essentially rigid support tube having a lengthwise rounded groove about which is disposed a membrane of elastomeric material. Compressed gas introduced between the support tube and membrane escapes via slits in the membrane. An elastically deformable flange of a cylindrical portion of a fitting with a plastic semi-rigid saddle portion is disposed between the distribution conduit and one of the aeration elements, and is disposed in a bore in the conduit. The fitting has an essentially flat saddle portion, one side of which rests against the outer surface of the conduit, and the other side of which rests against an end of the aeration element. A hollow bolt is securely connected to the aeration element and is guided through a bore in the fitting into the interior of the conduit, where it is provided with apertures.
