摘要： The invention relates to an articulated pipe connection for two conductingarts 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.

摘要： The invention relates to a pipe joint for connecting a first pipe part (1) and a second pipe part (2), in particular for an exhaust-gas system of an internal combustion engine, having a fastening means (3) and a sealing element (4) which has a sleeve (5) and a sealing ring (6). According to the invention, the sleeve (5) has a radially widened portion (8) at its first end (7) and can be pushed into the first pipe part (1) such that the widened portion (8) engages behind a circumferential constriction (11) of the first pipe part (1). The pipe joint according to the invention is suitable, in particular, for the gas-tight connection of exhaust pipes of motor vehicles.

摘要： A spring system for connecting two flanges (13, 14), for use especially in a motor vehicle exhaust system. The spring system is configured as an elastic, flexible clamp with functionally first (1, 2) and second (4, 5) U-shaped clamping jaws positioned opposite each other. This provides a spring system which is easy to assemble and economical to produce. To this end the spring system has the U-shaped arms (6, 7) of the clamping jaws (1, 2; 4, 5) having only locally very restricted areas (8, 9, 10) for direct application to the pieces (11, 13; 12, 14) to be joined by means of the clamp. Four application areas (8) exercising both clamping functions are present in at least one of the clamping planes (100 or 200), of which two areas are arranged in pairs and situate diametrically opposite each other.
