The invention relates to a discharge device (1) comprising a tank housing (3) having at least one outlet (4) at one end and having a drive means at the opposite end. A connector (6) can be placed over the outlet (4) on the discharge device. The connector comprises a releasable mounting device that can be released by manual pressure on two opposite side surfaces of the connector. One guide surface (9) is provided on each of the two opposite side surfaces, each being oriented diagonally to the longitudinal axis (L) of the discharge device (1) and spaced in the direction of the discharge device. The connector is placed over the outlet on the discharge device in a mounting position. The guide surfaces (9) are moved radially toward each other in a released position by pressure (F) on the side surfaces. The guide surfaces thereby slide on an edge (15) of the discharge device (1), and the force is diverted to the edge (15), so that the connector (6) is axially displaced away from the drive direction in the released position.
