Abstract: The invention relates to a golf tee assembled formed of a flexible rubber ball support shaft, an aluminum or plastic ground engaging spike and an aluminum retainer ring. The support shaft and spike each are provided with complementary planar flange and disc, respectively. The retainer ring is cup shaped and has a central bore. The central bore is made a size to receive the support shaft so the retainer ring can be moved to the flange and disk. The retainer ring has a shape which conforms to the shape of the flange. The planar surfaces of the flange and disc engage in abutting relationship and the retainer ring is crimped or folded around the flange and disc to thereby rigidly connect the support shaft and ground engaging spike to form a one piece golf tee unit.
