Abstract: A device for gripping a hollow body includes a freely-rotating shaft and a mandrel that is integral with the shaft. The mandrel itself includes: an end fitting; a radiator that is mounted directly on the end fitting; a crosspiece inserted between the end fitting and the radiator; an expandable ring mounted between the end fitting and the crosspiece; an elastic element mounted between the end fitting and the expandable ring; an insert made of a material with high thermal conductivity, set in a housing made in the end fitting and emptying onto a free end face of the former, with the insert extending up to the point facing the radiator.
