Abstract: A manifold, which comprises a body (2) with pipe fittings (3). The body (2) is at least mainly made of plastic material. The body (2) is formed such that it comprises ribs (5), which are most preferably arranged in the peripheral direction of the body.

Abstract: The invention relates to a pipe joint for joining pipes with a bent pipe or branch (1) comprising a body (2) having an inner diameter less than the exterior diameter of the pipe (4) to be joined, and sleeve portions (3a, 3b) having an inner diameter substantially equal to the exterior diameter of the pipe (4) to be joined. Thus a step is formed between the body (2) and the sleeve portions (3a, 3b). The sleeve portion (3a, 3b) is eccentrically disposed relative to the body (2) in such a way that at the outer edge of the pipe joint the height of the step between the body (2) and the sleeve portion (3a, 3b) is substantially equal to the wall thickness (e) of the pipe (4) to be joined, and at the inner edge of the pipe joint the height of the step is less than 0.5 times the wall thickness (e) of the pipe (4) to be joined.
