Each sealing strip (11) has an enclosed component with spring effect which pliably presses the strip against the side walls (6) of the channel. The component is completely enclosed in the flexible material, with the property that under effective sealing it holds the strip firmly against the side wall even where there are certain deviations in the wall sealing surface from the completely flat shape, and at temps. which cause the flexible material of the strip to harden, with the subsequent deteriorated location against the channel side wall. |
