The invention relates to a safety device for moving handrails consisting of a stop ( 5 ), arranged at the entrance of the handrail ( 1 ) assembled on a fixed railing ( 3 ) finishing the handrail, the stop ( 5 ) being connected to a rod ( 7 ) which can move longitudinally and is retractable against a spring ( 9 ), the device comprising a hinged outer lid ( 15 ) having locking pawls ( 19 ) for an inner lid ( 18 ), such that the outer lid ( 15 ) automatically tends to the open position due to the effect of the springs ( 17 ) affecting the hinge ( 16 ) when the stop ( 5 ) is retracted and the locking means ( 10 ) of the latter are released, whereas the inner lid ( 18 ), upon being released, also tends to the open position by simple gravity. In this way when a user does not let go of the handrail ( 1 ) when it penetrates the railing ( 3 ), he or she drives the stop ( 5 ) with his or her hand and the lids ( 15 ) and ( 18 ) are automatically opened, preventing injury to the hand of the user and causing the stop of the handrail through a microswitch ( 23 ).
