Abstract: A sealing plug arrangement for sealing a combined filling and degassing opening of an accumulator. The sealing plug arrangement includes at least one valve part, one valve holder, and one sealing plug. The valve part is arranged on the valve holder and forms an openable valve mechanism with the valve holder for sealing at least one interior space of the accumulator from the surrounding area upon pressurization. The sealing plug includes at least one fastening means for fixing to the filling and degassing opening and at the same time subjecting the valve part to a pretensioning force toward the valve holder. The valve holder includes at least one extension axially projecting toward the valve part which is formed as a circumferential sealing edge on a surface facing the valve part on which the valve part rests.
