Abstract
A double pipe connection is provided having a one-piece gasket (5), which extends sealingly into an intermediate space (1c) of one pipe end (1a) with an internal, transversely extending wall (5c), on one hand, and, also sealingly surrounds a partition (2c) of the other pipe end (2a), on the other hand. The two pipe ends (1a and 2a) are inserted into each other in the axial direction, and are held together with a locking bar (6) in a positive-locking manner. The cross section of the pipe connection may be non-round, e.g., rectangular. Since the pipe ends have no flanges and outer threads, they may be cut to any length, and shaping suitable for injection molding is possible. The double pipe connection is particularly suitable for liquid-bearing pipes on sanitary devices, e.g., drain fittings for wash stands.
