ABSTRACT:
A one-piece clamping shell for electric cigar lighters, which comprises a rolled sheet-metal body of tubular configuration, having open ends and a reverse-bend clinched seam extending longitudinally between its ends. At one of its ends the body has a radially inwardly extending flange means configured as a one-turn helical thread, said flange means having notches in it, one of which is bounded by edges that are located in planes spaced axially apart an amount essentially equal to the pitch of said thread, thereby to constitute in effect a nut adapted to be screwed onto an externally threaded shell at the rear of the cigar lighter.
