The invention relates to a drainage connector (1) having a cup-shaped housing (2) which comprises a housing base (3) and a housing wall (4). A connection geometry (5) is arranged on the outside on the housing wall (4) for inserting into a container opening, wherein an inlet pipe (9) of an inlet side (7) is guided to an outlet side (8) through the housing base (3) and an annular collecting chamber (10) is formed between the inlet pipe (9) and the housing wall (4). In order to discharge denser fluid which can accumulate in the collecting chamber, the housing (2) has a discharge channel (11), which leads from the collecting chamber (10) to the outlet side (8) and can be closed from the outlet side (8). The drainage connector is intended to be producible in a cost-effective manner at low cost and to have a low mass. For this purpose, the inlet pipe (9) on the outlet side (8) merges into an outlet pipe (13) which has a closing element (16) that can be moved between an open position and a closed position, wherein the housing (2) comprising the connection geometry (5), the inlet pipe (9) and the outlet pipe (13) is formed from plastic as a single piece.
