A dipped fusehead has its dipped head of ignitible material inserted into a protective cap of heat-shrinkable plastics material, for example irradiated thermally stabilized polyethylene, which is heat-shrunk around and into close contact with the head and is sealed around the body of the fusehead by means of a polyethylene sealing ring in the open mouth of the cap.
