Abstract: A lampholder, particularly for electric Christmas tree candles, comprises two substantially but not quite similar parts which are united with each other substantially on an axial plane, at least along a major portion of their axial extension. To permit automation of the mounting of contact blades and electric conductors connected thereto in the holder, as well as subsequent assemblage of the lampholder halves, one half only is provided with retention and stress relieving means for firmly holding the contact blades and the stripped ends of the conductors in said one half before as well as after the assemblage of the halves. In one embodiment intended for larger lamp bulbs one lampholder half is longer than the other axially, and terminates in an annular end portion having a through hole for the electric conductors.
