Abstract
The invention relates to a filter module comprising a number A of circular filter cell ( ), a number A−1 of spacer rings ( ), and two end rings ( ), whereby the filter cells ( ) and the rings ( ) are combined to form a stack while forming a central continuous channel ( ) using tension elements ( ) which are interspaced in the circumferential direction of the channel wall and which, on the inner side, engage on the end rings ( ) in order to transmit axial tension forces. According to the invention, tensioning elements comprised of strips ( ) with hook-shaped ends ( ) are provided for securely combining the filter cell that are arranged in a stack. Said hook-shaped ends can be fixed in the end rings by effecting an essentially radial hooking-in or engaging movement, In addition, means ( ) are provided which prevent an unintentional radial hook-removal or disengaging movement of the hook-shaped ends ( ).
