Abstract

To simplify the assembly of filter modules 10, the supporting tube 1 which carries the filter cells 9 is constituted in two pieces. Both the upper tube piece 4 and the lower tube piece 5 contain locking elements 7 which are received in correspondingly large recesses 8, thereby making possible a safe interlock as well as a relative axial movability of the tube pieces 4 and 5.
