The invention relates to a blow mould for transforming plastic parisons to form plastic containers, having a base part, a first side part and a second side part, wherein, in the assembled state of the blow mould, this base part together with the side parts form a hollow space, within which the plastic parisons can be expanded to form the plastic containers. According to the invention, at least one element of the blow mould has a first fastening section to which a first adapter element can be attached, which adapter element facilitates changing of the blow mould by means of a robot device, wherein this fastening section is formed in such a way that this adapter element can be attached releasably to this fastening section, and wherein this fastening section is formed in such a way that the blow mould can be arranged both with this adapter element and also without this adapter element on a transforming device for transforming plastic parisons to form plastic containers.
