A liquid dispensing device includes a dispensing end piece and a neck of a reservoir for storing the liquid, the end piece being attached to the neck, which has a tubular internal surface. The end piece has a tubular internal skirt that is mounted in the neck and defines, with the internal surface, at least one annular sealing zone, preventing the liquid from passing between the internal skirt and the neck. The skirt defines, with the internal surface, a separate zone for retaining shavings, which prevents shavings that are formed in the sealing zone while the end piece is being fitted into the neck from getting into the reservoir.
