ABSTRACT OF THE DISCLOSURE The ground water drain comprises a frame and a grating inserted in the frame. The grating has a central bar and a plurality of crossbars arranged normal to the central bar. Holding portions are provided in the frame over its support for the grating. Projecting portions formed on some crossbars project into the holding portions when grating is inserted into the frame. For the insertion of the grating, at least one projecting portion on one side of the grating is inserted into the corresponding holding portion and subsequently the opposite side of the grating is pressed down. The projecting portions have sloping faces which snap into the holding portions of the frame while the central bar is simultaneously elastic bent. Therefore the grating is positively secured in the frame and even when using an elastic material for the grating the latter cannot be moved to such an extent by the traffic travelling over it that it could pump out of the frame.
