An exhaust gas cleaning device (2) for an exhaust system (1) of an internal combustion engine with an exhaust gas cleaning element (7), which is arranged in a first tubular body (3), and with a second tubular body (4), to which the first tubular body (3) is detachably connected via a clamp connection (5). The clamp connection (5) includes a radially outwardly projecting first ring collar (8), formed at the first tubular body (3) and extending circumferentially in a closed form and a radially outwardly projecting second ring collar (9), formed at the second tubular body (4) and extending circumferentially in a closed form. A sealing ring (10) extends circumferentially in a closed form and is axially in contact with the first ring collar (8) and the second ring collar (9). A first ring body (11) is arranged on the outside at the first tubular body (3) and is axially in contact with the first ring collar on the side facing away from the sealing ring (10). A second ring body (12) is arranged on the outside at the second tubular body (4) and is axially in contact with the second ring collar (9) on the side facing away from the sealing ring (10). A clamp (13) extends over both the first ring body and said second ring body (11, 12) and tightens these axially towards one another.
