A back pressure flap valve arrangement is disclosed. The arrangement comprises a housing () having an inlet opening () and an outlet opening () adapted for connection of the housing () to a ducting (), and at least one side wall () extending along a flow direction through the housing () from the inlet opening () to the outlet opening (). A flap () is pivotably hinged about a shaft () thereby being movable between an open position and a closed position, said shaft () extending transverse the flow direction. At least one locking device () is fixedly mounted to the side wall () and comprises a locking pin () and a stopping member (). The locking pin () is movable between a retracted position and a locking position, and being biased towards said locking position. The stopping member () is movable from a stop position in which the stopping member () is adapted to hold the locking pin () in its retracted position, to a release position by the flap () acting on the stopping member () in case of a back pressure. Thereby the locking pin () is allowed to move into the locking position in which the locking pin () maintains the flap () in the closed position.
