An electric blanket or pad arrangement has a flexible pad ( 10 ) upon which a heating element ( 12 ) is mounted, the heating element ( 12 ) being connected, by a two core cable ( 16 ), to a control circuit ( 18 ), the heating element ( 12 ) including a dual element region ( 20 ) having a first, inner conductor ( 26 ), a second outer conductor ( 30 ), an inner insulating material layer ( 28 ) provided between the first and second conductors ( 26, 30 ), and an outer insulating material layer ( 32 ) encasing the second conductor ( 30 ), the inner insulating material layer ( 28 ) having a lower melting point than the outer insulating material layer ( 30 ), and a connecting element ( 22 ) having at least a third conductor ( 36 ) providing a series electrical connection between the first and second conductors ( 26, 30 ) at one end ( 12 <U STYLE="SINGLE">a) of the dual element region ( 20 ) of the heating element ( 12 ).
