Abstract
A connecting device for connecting two thermoplastic pipes together including a thermoplastic body having a resistive element having a wire mesh structure and connection terminals. Each of the connection terminals has a tubular rivet body made of an electrically conductive material. The tubular rivet body includes a collar integrally formed with a hollow shaft and a flanged portion bent to immobilize the resistive mesh after the connection terminals are riveted to the mesh. This increases the reliability of the connection terminals to the resistive mesh.
