A device for a filter has a filter pot, an adapter arranged to have filter cartridges hanging therefrom, a media-tight foil bag surrounding the filter cartridges and abutting at least indirectly in the filter pot, a head arranged above the adapter, a sealing device arranged between the upper edge of the filter pot and the outer marginal zone of the adapter, outflow volume means between the adapter and the head, a lid arranged to fit upon the pot and the sealing device, an elastic feed connector extending upwards from the head and communicating with the interior of the foil bag, and an elastic outflow connector extending upwards from the head and communicating with the outflow volume means, the lid having openings through which the feed and outflow connectors pass. First and second vertical cylindrical enclosing connector pipes, each with an inner surface which can be subjected to circumferential stresses, extend from the lid. The feed connector is arranged to fit in the first enclosing connector pipe and the outflow connector is arranged to fit in the second enclosing connector pipe. A hollow cone is arranged at the end of each of the conduits, which is subjectable to pressure stresses and has an external circumferential surface that is a steep cylinder-cone frustum that fits in its narrower zone into the feed and outflow connectors, respectively. An axially acting clamping device is arranged between each of the hollow cones and respective ones of the enclosing connector pipes.
