ABSTRACT:
A joint for a water-carrying pipe system, e.g. for a garden spray, has a joint shoulder with a disk-like part for each pipe end to be connected. The two disk parts are arranged on either side of the hose passed centrally through the joint. On either side of the joint, the hose is connected to the pipe ends in that it is passed through an opening, whose internal diameter is somewhat smaller than the external diameter of the hose. Thus, the hose engages flat on the openings of the pipe ends, so that this in itself leads to a liquid-tight seal.
