Abstract
Abstract An artificial tree, such as a Christmas tree, including two hollow trunk members sleeved together and having removable limb sockets angularly disposed in said members. A lighting system comprising wiring is arranged within the trunk members and wiring sockets are disposed within openings in the trunk members adjacent the limb sockets and retained therein by spring clip members arranged in the trunk members opposite to the wiring sockets. Limbs extend outwardly from the limb sockets whereby bulbs and wiring extending from the wiring sockets may be secured thereto. Top and bottom caps are provided on the trunk members and the latter is sleeved over a supporting base.
