A method for holding together, in its closed state, a blow mold of multipiece design of a blowing station for the blow molding of containers from preforms made of a thermoplastic material using a compressed air-operated mold clamp exerting a holding-together force. The mold clamp is pressurized with compressed air for the purpose of and for the duration of the generation of the holding-together force. The blowing station has a relief valve which can be controlled by control compressed air from a control compressed air line. The mold clamp is pressurized at least at times with control compressed air from the control compressed air line.
