The heating wire is embedded in both surfaces of a disk-shaped core, in each case following the course of a spiral-shaped groove, and the core having the heating wire is joined with the molded connection piece. The disk-shaped core is formed of a material which, on melting, combines itself with the material of the molded connection piece.
