FIELD: mounting hardware.
SUBSTANCE: invention relates to a fastening equipment, namely to the fastening elements of additional layers, for example additional layers of thermal insulation, to a supporting base. Device for fastening is made in the form of a sleeve with a longitudinal hole and a disc element, at least the diameter of a part of the length of the longitudinal hole allows additional element to be assembled therein, which is a rod intended for mounting in longitudinal hole. Element is made on the wall of the longitudinal hole to interact with at least one response element in said additional element in such a way that the additional element is kept in the opening of the distance zone in the transport position. Specified element on the additional element is a local protrusion, for example, is a point protrusion located closer to the end of the additional element. Surface of the protrusion facing the entrance to the longitudinal hole of the fixing device is inclined, and the surface facing the exit from the longitudinal hole not less than perpendicular to the surface of the additional element or hanging above the surface of the additional element.
EFFECT: invention is directed to the possibility of using a material with a high coefficient of thermal expansion.
