The invention refers to a plant and a holding device in connection with heat treatment of articles ( 3 ), which is at least partly manufactured in a thermosetting composite material. The holding device, which is comprised by the plant, includes a base element ( 1 ), and intermediate element ( 2 ), which rests on the base element ( 1 ), and at least a support member ( 4 ), which is fixable to the intermediate element ( 2 ) and arranged to support said article ( 3 ) on the intermediate element during the heat treatment. The intermediate element ( 2 ) is manufactured in a material which has a neglectable thermal extension at least up to a temperature level, at which the heat treatment is intended to take place. Furthermore, the intermediate element ( 2 ) is displaceably positioned on the base element ( 1 ).
