FIELD: construction.
SUBSTANCE: invention relates to construction of buildings and structures, in particular to devices for heat-insulating materials attachment to bearing structures. Fastener for heat-insulating materials attachment contains a pin with a cylindrical body and plastic thermal protective head, solid plastic retaining element, which consists of a pressure plate, bush, guiding the pin, and a seat in the form of hole arranged between the bush and pressure plate for arrangement of the pin head after its input. Pin head is equipped with an external expanding ring on the side of the pressure plate. Inlet part of the hole of retaining element is provided with mating stepped expansion. In the pin head there is a socket made in the form of a polygonal blind hole. Inside the retaining element at the bottom of pin seat there is a projection made in the form of an annular platform. Pin body can be plastic or metal.
EFFECT: higher reliability of a fastener.
