The pipe(2) sits on a clamping ring(4) that lies, under radial pressure, on the inner wall(11) of the support(1) together with a key-lock element(9) that stems from the outer layer and which works together with a counter key-lock element(12) of the support. The key-lock element may be built ring-shaped and be fixed on the outer layer of the clamping ring. The key-lock element may be made from metal and have a partially circle-shaped cross-section. The counter key-lock element may have a depression in the inner wall of the support.
