ABSTRACT:
During injection molding of a plastic key tag or the like having an integral strap appendage with longitudinally spaced apertures formed therein for accommodating a fastener securing the strap in a looped configuration, a weakened weld line extending between the apertures is created. To discourage eventual splitting of the looped strap along this weld line, a relieved section is molded in the strap at a location calculated to reduce the lateral tensile stresses acting on this weld line.
