Abstract
A shielding element, which comprises at least two sections that are embodied to be linearly connected to each other in abutting fashion on at least one contact surface so as to enclose a three-dimensionally shaped profile or pipe segment of an exhaust line of an internal combustion engine over a certain length when in use. In order to modify a shielding element of the above-mentioned type while amplifying its effect with other positive properties, it is proposed for the sections of the shielding element to each comprise at least one electrical heating system, which, in an installed position, is thermally directed at the pipe segment that is to be enclosed.

A shielding element, comprising at least two sections that are embodied to be connected to each other in abutting fashion on at least one contact surface so as to enclose a three-dimensionally shaped profile or pipe segment of an exhaust line of an internal combustion engine over a certain length when in use,
- wherein the at least two sections of the shielding element each comprise at least one electrical heating system, which, in an installed position, is positioned proximate to and thermally directed at the three-dimensionally shaped profile or pipe segment that is to be enclosed, and
- wherein the at least one heating system includes at least one resistance conductor provided with an electrical insulation that electrically insulates the at least one resistance conductor relative to the three-dimensionally shaped profile or pipe segment, with a meandering path extending over a certain length in a flow direction of exhaust.
