Abstract: A device for correcting interchanged pipe connections in a sink or bathtub faucet has a housing 1 with passages 10,11 for hot and cold water. From each passage tap lines 14, 15 run to a cylindrical recess 2 having a flat bottom 22. Discharge pipes 5,5' for mixed water are also led to the bottom by tap lines 16,17. The two feed tap lines 14,15 and, diagonally opposite, the discharge tap lines 16,17, empty centrally. A connector 6 installed in the recess 2 is provided with passages 34-37, which starting from annular channels 18-20 located at the bottom, lead to openings of feed pipes 24-27 in a fitting housing 9. The connector has two pieces, a central part 7 installed interchangeably by 180.degree. in a peripheral part 8. The connector 6 can also be rotated by 180.degree. on the housing 9, or by 360.degree. together with the housing.
