ABSTRACT:
In an electric hotplate (1) flexible connecting leads (22), whose outer ends form connecting members (29) for connection to appliance lines, are so connected in positionally secured manner to short, bent pins (13) that the connection points or junctions (28) are directly accessible from the outside by welding tongs or the like for producing welded joints directly adjacent to an insulator (9). For the conection of these inner ends (25) to the pins (13) in such a way that they directly engage on the insulator (9), an orienting device (30) is provided as an auxiliary tool and can be oriented with a fork-like centering member (40) with respect to the insulator (9) and has orienting receptacles (42) for the engagement of end portions of the inner ends (25) of the leads (22).
