Zusammenfassung:	A transporting device for holding and cooling as till warm preform includes a frame (1) holding cooling tubes (5) with internal cooling passages (22). Inside the cooling tubes (5) are elastically deformable preform holders (19) with circular cross-section inner surfaces (19c) or pairs of interacting semi-circular inner surfaces. The internal surface (19c) can be varied between an open position and a preform (10) holding position by exerting external force. In the holding position the internal surface (19c) is elastically pressed against the preform (10) and in the open position has a cross-section greater than that of the preform (10). The holder (19) also forms part of the cooling channel (22) wall.
