In the case of a tool for grasping a hollow article blow moulded in a blow moulding machine, for further conveying it to a succeeding station, the aim is to carry out the retooling to a different mould rapidly and with simple means. For this purpose, a removal mandrel is proposed, which can be introduced into the neck orifice of the hollow article, can be subjected to compressed air and has a sleeve element which is covered with a jacket of elastomeric material. On compressed-air supply, the compressed air passes below the jacket and expands it elastically until the jacket comes to bear against the inner wall of the neck orifice, and a firm connection is thus formed between the hollow article and grasping mandrel. The removal mandrel is exchangeably attached, by means of a quick-closure coupling of a known kind, to a carrier head, by means of which the removal mandrel with the hollow article can be transported to a succeeding station.
