A heating element comprising a plurality of ceramic components strung together on a heating wire to form a flexible structure, adjacent ceramic components comprising integrally formed mating projections and depressions. The element comprises ceramic components of a first type each having a body defining two generally parallel passages therethrough, both passages terminating at one end in a common slot, one passage terminating at the other end in a depression, and the other passage terminating at the other end in a projection; and ceramic components of a second type having a body defining a passage therethrough terminating at one end in a depression and at the other end in a projection, the components of the first type forming two parallel rows, the components of the two rows being staggered relative to each other, and the components of the second type being arranged to fill spaces formed at the ends of the two relatively staggered rows such that the two rows of components are of substantially the same length and each passage in one row is aligned with a respective passage in the other row, the components being oriented such that the projections and depressions of adjacent rows interengage, and the wire being arranged to pass through the passages in each component and to lie in the slots in the components of said first type. .
