1. A magneto-inductive flow measuring device having a measuring transducer, wherein the measuring transducer comprises: a measuring tube, through which a measured substance can flow;a magnet system for producing a magnetic field;at least one electrode inserted into the measuring tube for registering an electrical voltage; anda securement means, which serves for securing said at least one electrode to said measuring tube, wherein:said securement means is at least partially composed of plastic, and said measuring tube is at least partially composed of plastic, both securement means and said measuring tube forming plastic portions;andsaid securement means is connected to said measuring tube at their plastic portions, by plastics welding joints produced by a plastic welding technology. 2. The magneto-inductive flow measuring device as claimed in claim 1, wherein: said at least one electrode has a flange, with which said at least one electrode lies against said measuring tube. 3. The magneto-inductive flow measuring device as claimed in claim 2, wherein: said measuring tube has a bore surrounded by a seat; andsaid at least one electrode is inserted into the bore. 4. The magneto-inductive flow measuring device as claimed in claim 3, wherein: said flange of said at least one electrode lies at least partially on said seat. 5. The magneto-inductive flow measuring device as claimed in claim 3, wherein: said securement means is connected with said seat. 6. The magneto-inductive flow measuring device as claimed in claim 2, wherein: said securement means lies at least partially on the flange of said at least one electrode. 7. The magneto-inductive flow measuring device as claimed in claim 1, wherein: the plastics welding technology involves one of the following technologies: ultrasonic, resistance, stud, laser, electron beam, friction and/or heat welding technology. 8. The magneto-inductive flow measuring device as claimed in claim 1, wherein: said securement means is embodied in such a manner, that, by said securement means, said at least one electrode is arranged in a desired position. 9. The magneto-inductive flow measuring device as claimed in claim 1, wherein: said at least one electrode has at least one sealing element, which seals said measuring tube in the region of the bore. 10. The magneto-inductive flow measuring device as claimed in claim 9, wherein: said at least one electrode has an electrode head and an electrode shank, and that said sealing element is partially inserted in a cavity of said electrode shank. 11. The magneto-inductive flow measuring device as claimed in claim 9, wherein: said at least one weld lip and/or a mash joint is provided on said securement means and/or said measuring tube; andsaid weld lip and/or the mash joint serves to affix said securement means to said measuring tube.
