<p>1. Shaped connecting part, in particular a boring saddle, which is made of thermoplastic synthetic material and which is provided with a disk-shaped heating element (1) which has a resistance wire (2) which extends in spiral shape and through which an electric current is conductable in order to manufacture a weld joint between the shaped connecting part and an object to be connected with this, wherein the core (1) which has the heating element (2) is capable of being connected together with the shaped connecting part (3), and the disk-shaped core (1) is made from a material which, on melting, fuses with the material of the shaped connecting part (3), characterized in that the resistance wire (2), following in each case a spiral-shaped channel, is embedded into both surfaces of a disk-shaped core (1).</p> |
