Abstract

The invention relates to a device (3), for sealing the discharge end of a pipe (1) in an exhaust system of an internal combustion engine, which defines a passage (2) for the exhaust gases. Said device (3) comprises a valve (4) embodied to seal the discharge end of said pipe and means (5) for returning said valve (4) to the closed position. Said device (3) comprises means (6) for holding the valve (4) in the closed position, said holding means (6) being distinct from the return means (5) for the valve (4).
