Abstract

The invention relates to an articulated pipe connection for two conducting arts of a motor vehicle which comprises spherical connecting pieces for joining the two conducting parts and has at least on one connecting piece a flange-shaped connecting piece abuttable axially against the latter, said connecting piece being connected with spring tension by spring means with the other connecting piece, with the connecting pieces being held together by the spring means with a pretensioning force. In order to design a device for linking two tubular connecting parts in such fashion that, with constant reliability of the pipe connection, much improved mountability of the pipe connection and a simultaneous considerable reduction in their manufacturing costs can be achieved, it is proposed according to the invention that the spring means comprise a curved washer, by which the connecting piece is simultaneously formed, and the spring means also have at least one clamp that is in an active relationship with the other connecting piece and engages the curved washer or is permanently connected therewith.
