Abstract

1. A pipe connection for the localised laying of thin-walled line pipes made of corrosion-resistant or high-alloy rustproof steel for water and heating installations, with a deformable connecting sleeve (2), also thin-walled, which is pushed onto the pipe ends (11, 12) and is made of the same type of material, the ends of which are formed as tori and have a sealing ring (3) disposed therein, surround the pipe ends (11, 12) with a press fit, and which has a copper working part (1) serving for cathodic protection against corrosion and which is in electrically conductive contact with an area of the pipe ends (11, 12) and the connecting sleeve (2), characterised in that a copper ring (1) is disposed inside the connecting sleeve (2) on the outer end of each pipe end (5).
