The invention concerns a conduit element made of metal for uncoupling high frequency vibrations in connection with exhaust gas conduits of motor vehicle internal combustion engines. To improve the uncoupling of these high frequency vibrations, the conduit element of the invention basically comprises a screw thread-shaped or annularly undulating short corrugated sheathing hose of high rigidity inserted into the exhaust gas conduit, as well as a knitted jacket placed on the waved corrugated sheathing hose segment in a force-locking or form-locking manner.

[ What is claimed is:] [1.]1. A conduit element for uncoupling high frequency vibrations in connection with exhaust gas conduits of motor vehicle internal combustion engines, comprising a short segment of screw thread-shaped or annularly waved corrugated metal sheathing hose (3, 11) of high rigidity for insertion into an exhaust gas conduit and a knitted jacket (7, 13) installed force-locking or form-locking upon the waved corrugated metal sheathing hose segment, wherein the segment of corrugated metal sheathing hose, when inserted in an exhaust gas conduit, has a length and rigidity effective to uncouple vibrations which may occur in a frequency range of 1000 Hz to about 4000 Hz.
