1. A mixer for a device for selective catalytic reduction of exhaust gases from internal combustion engines, for uniform distribution of a reducing agent in the exhaust gas stream that is introduced into said exhaust gas stream at the catalyst inlet, wherein said mixer comprises:
a structure of mixer elements through which the mixture of exhaust gas and reducing agent is configured to flow,
wherein said mixer elements are adapted for direct electrical heating with an electric current flowing through them due to their electrical resistance, and
wherein said mixer elements are provided with tabs that are received between insulation plates that are held between pipe section flanges of pipe sections of a housing of said mixer.
