The rack is provided with a central opening (5) for a flow, and with several relatively small openings, through which fastening hooks (12) may be inserted, which are designed with protrusions (15,16), intended to penetrate, at the lower side of the rack, a penetrable working element (18) like a sponge, cork etc, and to keep same against the rack.
