Electric heating element for fusing thermoplastic materials

A device and method for covering pilings of piers and the like includes a plastic cover or sheet which is wrapped around the piling for protecting the piling against rot, weather and wear. The plastic sheet ends overlap as they wrap around the pile. The ends are sealed and secured by a heatable strip extending between the overlapped ends of the sheet and which forms a fused plastic seam between the overlapped ends as the sheet is held tightly about the pile. A strap and a bar which presses over the heatable strip is provided for temporarily cinching the plastic sheet tightly about the pile and holding it while the heat fusing occurs.
