Abstract
Two pipe sections (1-4, 31, 32) of a high-pressure line each comprise a fluid-tight inner jacket (9) made of a thermoplastic material and a reinforced outer jacket (10). The innner jackets are attached to one another by means of a fluid-tight weld (5-8, 33) and the outer jackets are each connected to one another by means of a connecting sleeve (16, 17, 25, 26). The connecting sleeve comprises shells which have serrations (15, 27) on the inside, as well as clamping means (13, 14, 28-31) for clamping the shells on the pipe sections in such a way that the internal serrations (18, 27) are made to interact with the outer jackets of the pipe sections.
