Attachment of metal and plastic parts of an implement handle

Abstract

A hollow, cylindrical, handle is substantially permanently connected to a end piece by insertion into the distal end of the handle of a first axial section of the end piece and inwardly deforming portions of the handle wall inwardly into indentations formed in the outer surface of the end piece. The end piece includes a shoulder at the juncture of the first section with a second section limiting the extent of insertion of the end piece into the handle and the indentations are formed, preferably on diametrically opposite sides of the first section, at a known axial distance from the shoulder. Visible indicia are placed on the outer surface of the second section in axial alignment with the indentations. The positions at which the handle wall is inwardly deformed is determined by the known distance from the shoulder (distal end of the handle) and in axial alignment with the indicia on the second section. In the disclosed embodiment, the indentations are elongated in a direction perpendicular to the central axis of the end piece and the visible indicia comprise flat surfaces in planes parallel to the central axis in an otherwise generally cylindrical outer surface of the second section. An O-ring provides a seal between the handle and end piece and the latter is formed with a through bore in applications where a liquid is to be supplied to an applicator or other tool mounted on the end piece.
