An assembly for securing and sealing a dispenser to a flanged container is provided. The assembly includes a sealing collet formed from a resilient deformable molded polymeric material. The sealing collet has an outer surface having an outer diameter, and also has a continuous downwardly extending skirt having a bottom portion thereof extending radially outwardly. The assembly also includes a retaining collar formed from a substantially rigid material, which has a sleeve about its periphery having an inner surface with a diameter sized to encase the skirt of the sealing collet. The retaining collar is slideable through a path of movement over the sealing collet to an assembled position. The sleeve deforms the bottom portion of the skirt radially inwardly to a position under the flange as the retaining collar is slid to the assembled position in order to maintain the sealing collet and the retaining collar in the assembled position and to maintain the seal between the sealing collet and the flange. A plurality of annular splines, grooves or a combination thereof are provided on inner surface of the sleeve, and are positioned to engage the outer surface of the sealing collet when the retaining collar is in the assembled position.
