The invention relates to an abseiling device comprising a rope guide pulley (2) which is rotationally mounted in a housing (1) and is connected by a toothed wheel (4) to two toothed shafts (5, 5') of centrifugal power braking elements comprising pairs of brake blocks (8, 8') acting on the device housing (8, 8') and comprising brake boots (10, 10') and additional safety brake boots (10"). The brake blocks of each pair are maintained in a rest position by means of a magnet (11) and an iron core (11'), which are disposed in the opposite front sides (8") of the brake blocks.
