Metal honeycomb structure (1), especially a catalyst support for motor vehicles with internal combustion engines, with walls which form a plurality of channels (9) through which a fluid can pass. The honeycomb (1) has a length (l) and is arranged and secured in at least one inner (2a, 2b, 2c) and an outer casing pipe (3). In addition, the inner casing pipe (2a, 2b, 2c) is divided into at least three partial sections, i.e. a first (2a) partial section lying substantially only along a part of the length (l) of the honeycomb on the outside, a second (2b) flared partial region and a third (2c) lying on the inside of the outer casing pipe (3). The bent shape of the inner casing pipe means that the honeycomb (1) and the outer casing pipe (3) can be thermally and mechanically separated, thus ensuring that the securing system has a long service life even in extreme operating conditions. |
