1. A process for joining a connection component together with at least one other component by welding, each of said connection component and said at least one other component comprising a body made of a heat-fusing plastic, said process comprising:

  • placing opposite one another contiguous surfaces of said connection component and said at least one other component, said contiguous surfaces defining a welding zone;

    providing said connection component with a resistive foil of electrically conductive material for the circulation of a current in said welding zone, said resistive foil being embedded in said connection component and being capable of splitting at a temperature substantially equal to a predetermined welding temperature;

    circulating an electrical current through said resistive foil for heating said components to said welding temperature;

    splitting said resistive foil in response to said temperature, said splitting of said resistive foil causing an interruption of said electrical current, whereby said electric current is terminated when said welding temperature exists in said welding zone.
