This heating cover for vulcanisation comprises two plates 2, 3 made of special heat-insulating materials which are vulcanisable and heat-welded with the positioning between them of a fabric 4 preferably made of glass fibres and heating elements 5. The heating element 5, which is a metal wire distributed over the whole surface of the cover, has a crimped shape with a zig-zag or similar profile, so that it can easily be deformed in order to take up the expansions which are produced during the vulcanisation, a thermocouple which monitors the operation of the cover also being disposed between the plates 2, 3. Application to repairing tyres. <IMAGE>
