This invention relates to a braking device (10) for a passenger conveyor comprising at least one movable part (12). The braking device (10) comprises a braking element (18) having a braking portion (34) engageable with the movable part (12) of the passenger conveyor. The braking element (18) is movable in a first direction into a position in which the braking portion (34) engages with said movable part (12) of the passenger conveyor. The braking element (18), in a state in which the braking portion (34) engages with the movable part (12) of the passenger conveyor, is movable in a second direction from a position of initial engagement of the braking portion (34) into a braking position of the braking element (18). The movement in the second direction is driven by movement of the movable part (12) of the passenger conveyor.
