Abstract

The invention relates to a filter module comprising a number A of circular filter cell (1), a number A−1 of spacer rings (3), and two end rings (4), whereby the filter cells (1) and the rings (3, 4) are combined to form a stack while forming a central continuous channel (2) using tension elements (5) which are interspaced in the circumferential direction of the channel wall and which, on the inner side, engage on the end rings (4) in order to transmit axial tension forces. According to the invention, tensioning elements comprised of strips (5) with hook-shaped ends (6, 13, 14) 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 (10, 11) are provided which prevent an unintentional radial hook-removal or disengaging movement of the hook-shaped ends (6, 13, 14).
