The invention relates to a safety device for a tank. A device for limiting the filling of a tank for liquid, comprising in particular a hydraulic stop valve, is characterised in that the said valve comprises a control chamber (8) which, when its internal pressure is substantially equal to the pressure of the flow of liquid to be stopped, is closed by means of a valve member (3), the seat of which is laid against the wall of the valve under the action of a spring (9) placed in the said control chamber. Application to the handling of all liquids and to hydrocarbon tanks in particular. <IMAGE>
