SUBSTANCE: plastic drainage gutter 1 has a U-shaped profile in the cross section. In the upper part of lateral sides of the gutter 1 there are longitudinal horizontal bearing ledges 2. At the first end face 3 of the drainage gutter 1 a docking ledge 4 is made. In the upper part on both lateral sides of the external surface of the docking ledge 4 longitudinal vertical thrust ledges 5 are made. In the lower part of the external surface of the docking ledge 4 a longitudinally basing ledge 6 is made. At the second end face 7 of the drainage gutter 1 a docking ledge 8 is made. In the upper part of the lateral sides of the docking ledge 8 holes 9 for the longitudinally basing ledges 5 of the docking ledge 4 of the first end face 3 are made. In the lower part of the docking ledge 8 a hole 10 for the longitudinally basing ledge 6 of the docking ledge 4 of the first end face 3 is made. The longitudinal vertical thrust ledges 5 are located on elastic latches. The elastic latches are formed by U-shaped 11 or L-shaped 12 cuts in the sidewall of the docking ledge 4 of the first end face 3.
