In a retaining unit for fixing a heat insulation element (5) to a supporting structure (4), which comprises a draw- stem (2), a tightening piece(3,6) for attaching the draw- stem (2) to the supporting structure (4), and a clamp(12) for attaching the heat insulation element(5)to the daw-stem (2), the clamp having a ball-and-socket type clamping disc (12) with a nest (12a) and a passage - opening (12b), and a carrying piece (11a) with a round head(ll) adapted to be fitted in so said nest (12a) in a way allowing it to turn around, the carrying piece (11a) being adapted to be pushed through said passage - opening (12b), it is foreseen the external surface of the draw-sterm (2) is roughened (1), that a metal female cone (3) is attached in a fixed position to the end of the draw- stem (2) next to the supporting structure (4), and that a cylinder- footed tightening wedge (6) pulled onto the draw- stem (2) is allocated to the female cone (3), so that the tightening piece is formed by the female cone (3) and the cylinder- footed tightening wedge (6) together, while in the carrying piece (11a) of the round head (11) there is a conical hole (lib) into which clamp jaws (9) with a positioning hook (13) are fitted, the roughened (1) surface of the draw- stem (2) being in contact with the clamp jaws (9). |
