Method for insulating connecting sites in pipelines comprises placing an assembly mandrel (2) on a pipe end to be connected, rolling a flexible insulating tubing (3) over the mandrel onto the pipe, connecting each pipe end together using a connector (4), and rolling the insulating tubing over the free metallic pipe surface and connector in the rolling off direction. Preferred Features: The pipe ends are deburred before being joined. The insertion depth (E) for the connector is set using the end of the mandrel on the pipe side and is marked accordingly.
