Abstract (en)
[origin: EP1274282A2] The heating element (1) has a silica based tubular envelope open at both ends, and a wound resistance wire (4) inside the envelope (2). At least one of the ends (6) has an increase or reduction in its diameter for pressure gripping onto a housing or chassis (10) of the cooking appliance. Modification to the diameter of the end of the envelope is done by local heating of the envelope.
