CONNECTING LEAD FOR A PROBE

Described is a connecting line for a measuring sensor, in particular for a measuring sensor for determining a physical property of a gas to be measured, such as the temperature or the oxygen concentration in the exhaust gas of internal combustion engines, including a jacket tube, at least two electrical conductors disposed in the jacket tube and further including insulating means which electrically insulate the electrical conductors from each other and from the jacket tube. In order to use unsheathed, bare metal wires as electrical conductors and to prevent short-circuits between the conductor and the jacket tube, as well as to ensure the flexibility of the jacket tube during installation, the insulating means include a plurality of insulating members which are centrally supported on each other and contain at least two through-holes for passage of the electrical conductors; the central supports being designed in the manner of a ball-and-socket joint so as to allow the insulating members to tilt with respect to each other around the supports.
