摘要

Connecting pipe for connecting a pipeline to a heating body comprises an outer pipe (2) with a large diameter and an inner pipe (7) with a small diameter. Preferred Features: The inner pipe is sealed off from the outer pipe via annular seals (4) but can still be displaced within the outer pipe. Spacers (3) between the inner pipe and the outer pipe serve as guides for the inner pipe in the outer pipe and prevent pressure loading of the annular seals. A fixing device (5) fixes the inner pipe against the outer pipe.
