ABSTRACT:
A socket and changeable bulb housing snap fastener for Christmas light strings includes a bulb housing with at least one tongue and a corresponding number of T-shaped male members. An annular outer flange is formed on the socket. The T-shaped male member has a snapping head and is formed on an outer periphery of an annular hollow engaging portion of the bulb housing. The tongue is made of insulating material and extends radially and outwardly from an outer periphery of the outer flange. A rectangular slot, having a width slightly less than a maximum width of the snapping head of the T-shaped male member, is formed on the tongue adjcent to a free end of the tongue. A V-shaped groove is formed on an upper side of the tongue at an end opposite to the free end and extends transversely to a length of the tongue. The slot is engageable with the T-shaped male member by bending the tongue upwardly about the V-shaped groove and pushing the tongue against the T-shaped male member, such that the snapping head is forced through the slot.
