Provided is a sealing unit for sliding onto a water outlet (38) with formation of a fluid-tight connection with a water hose or similar that is equipped with said sealing unit (1), and that comprises at least one outer sealing ring (3) consisting of an elastic material and having an annular base body (4), from the area (5) of which that is oriented towards the center, a circumferential outer sealing collar (6) extends towards the center, which collar is moreover inclined in the insertion direction (17) and encloses an opening (16) through which the water outlet (38) can be inserted, and a sliding funnel (8) comprising an annular circumferential base body (9) resting upon the exterior of the base body (4) of the sealing ring (3), and from which several lobe-type tongues (11) articulated to the base body (9) by means of their bases (10), extend radially inwards, which tongues rest upon the exterior of the outer sealing collar (6) and form a kind of funnel together, and the free ends of which enclose the opening (16) for the insertion of the water outlet (38). Said inventive sealing unit is characterized in that the tongues (11), on their free ends (12) have a thickened portion (13) provided with a supporting surface (14), which is arranged approximately perpendicular to the plane of the respective tongue (11) and which is arranged approximately perpendicular to the radial longitudinal direction of the respective tongue (11), and the outer sealing collar (6) passes over radially inwards into a prolongation (18), which extends towards the center beyond the free ends of the tongues (11) of the sliding funnel (8), and which is configured on its free edge as a torus (41). Thus, an improved sealing effect between the water outlet and the sealing unit is achieved.
