Abstract
A safety device for closure elements () on pressure-medium-containing tanks, in particular on hydropneumatic devices such as hydraulic accumulators, has a screw connection provided as a closure device on a filling or checking port. The screw connection has a closure screw () threadedly engaged on the port () and blocking the port () when the screw connection is tightened and opens the port () when a flow path is released. A device () limits the free movement path of the closure element () when moved out of a closed position as a result of occurring overpressure.
