Abstract
Process for fastening an accessory to a hollow body obtained by molding a molten plastic parison and using a plastic connector comprising coupling means for the accessory and a stop surface intended to limit the penetration of the connector into the molten plastic, according to which the stop surface is provided with a curved double lip (or one-piece part having two concentric curved edges, i.e., two protuberances located preferably at its periphery, which are concentric and are in relief relative to the remainder of the part) and the connector is welded to the inner wall of the parison using this double lip.
