Abstract
A device for cleaning vehicular exhaust gas, in particular a diesel exhaust particle filter, comprises a filter body which has gas flowing through it, is composed of cuboid individual bodies and has been machined on the circumferential surface. Ring segment type clamping members made of warp-knitted or woven filaments rest against the end face of those individual bodies which have undergone more machining than other individual bodies situated on the outer circumference of the filter body.
