1. An exhaust gas heating arrangement for an exhaust gas system of an internal combustion engine, the exhaust gas system including a guide for conducting a flow of exhaust gas therethrough and said guide defining a wall bounding the flow of the exhaust gas, the exhaust gas heating arrangement comprising:
a heating conductor element arranged in said flow of exhaust gas in said guide;
at least one bushing arrangement in said wall;
said heating conductor element being guided through said wall in the region of said bushing;
an electrical connection line disposed outside of said guide;
a connecting arrangement for connecting said heating conductor element to said electrical connection line externally of said guide;
said connecting arrangement including:
said heating conductor element including a heating conductor element conductor element having an exposed end segment defining a first connecting region;
said electrical connection line including a connection line conductor having an exposed end segment defining a second connecting region;
a connector electrically connected to said exposed end segment of said heating conductor element conductor element and electrically connected to said exposed end segment of said connection line conductor so as to connect said exposed end segments to each other;
a shielding sleeve surrounding said first connecting region, said second connecting region and said connector;
said shielding sleeve having first and second sleeve end portions; and,
said shielding sleeve being connected to said heating conductor element in said first connecting region in said first sleeve end portion and being connected to said electrical connection line in said second connecting region in said second sleeve end portion and so shielding said exposed end segment of said heating conductor element conductor element and said exposed end segment of said connection line conductor and said connector against external influences,
wherein said heating conductor element further includes a sheath made of metal material and surrounding said heating conductor element conductor element in said first connecting region with the interposition of electrically insulating material,
wherein said shielding sleeve is connected to said sheath in said first sleeve end portion by material cohesion.
