The present invention relates to a drain which comprises an inlet member (1), a grating (13) or cover plate laid loosely or detachably on top of the inlet member, and an outlet member (2). To achieve a short line of contact between the surface covering's sealing layer (6) and the drain while at the same time the sealing layer is fastened by means of a clamping ring (5) or a bonding flange, thereby reducing the risk of leakage and affording the possibility of connecting an aesthetically more pleasing inlet member (1), the inlet member (1) takes the form of an elongate or trilateral plate-like element (11) disposed on top of the sealing layer or the sealing layer (6) and the clamping ring (5) and provided with a recess (12) for flow communication with the outlet member (2). The present invention relates also to an inlet member (1) for a drain as above.
