FIELD: construction.
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. Fastening device is made in the form of sleeve 1 with longitudinal hole 2 and disk element 3. At least the diameter of a part of the length of the longitudinal hole allows additional element 4 to be assembled therein, which is a rod intended for mounting in longitudinal hole 2 and interaction with spacer 5. At one end of additional element 4, the element forming cap 6 is made, and seat 7 for this cap 6 is made in the body of the sleeve. Surface of cap 6 facing the wall of seat 7 and the wall of seat 7 which is located opposite to this surface are conical in such a way that, in the mounted state of additional element 4, the conical surfaces of cap 6 and seat 7 come into contact in the section of their area 8.
EFFECT: fastening device is proposed.
