A method of manufacturing a plastic sleeve, particularly an expanding sleeve, includes injection molding the plastic sleeve with an inserted core in an injection molding tool, subsequently pulling the core and inserting the metal pin without heads, cones or the like into the bore of the plastic sleeve placed in the injection molding tool, and subsequently injection molding in the same injection molding tool the heads, cones or the like on both ends of the metal pin, and subsequently injecting the plastic sleeve with inserted metal pin from the tool.
