ABSTRACT:
A one-piece sheet metal base for a tubular lamp having pinch-sealed ends is adapted to be simply pushed onto the lamp end by hand. It comprises a flat portion having longitudinally extending side wall portions exceeding slightly in height the thickness of the pinch seal with inwardly turned underbeveled extensions which resiliently grip the pinch seal for frictional retention. A distal end wall portion has a forwardly turned lip adapted to overlie a pigtail attached to the inlead. Mitered corners on the underbeveled extensions and on the end wall provide a passage for threading the pigtail through the base.
