Mixer arrangement for mixing an injection medium injectable by an injector with the exhaust gas of an internal combustion engine

A mixer arrangement for mixing an injection medium injectable by an injector with exhaust gas of an internal combustion engine, comprising:

• a first exhaust gas guide section and a second exhaust gas guide section, through each of which the exhaust gas from the internal combustion engine is guidable;
• a mixing pipe fluidically connecting the first exhaust gas guide section to the second exhaust gas guide section, wherein the mixing pipe has an opening through which the injection medium is injectable from the injector into the mixing pipe;
• and
• a sleeve element surrounding the mixing pipe at least partially, so that a gap is formed between the sleeve element and the mixing pipe, wherein the gap is fluidically connected to the first exhaust gas guide section,
• the mixing pipe being longer than the sleeve element,
• wherein the sleeve element has contact sections with which the sleeve element is seated on the mixing pipe, the sleeve element being in contact with the mixing pipe only with the contact sections,
• wherein the contact sections are designed as a plurality of spring tabs.
