A golf tee includes an insertion part for insertion into a ground, a supporting tube for holding a golf ball up, and a connecting tube for connecting the supporting tube to the insertion part with; the supporting tube has an annular protrusion near a bottom on an inner side; the connecting tube has several elongated gaps, which extend longitudinally from a top to a lower portion to divide an outer side of the tube into separate sections; the connecting tube has several detaining bumps on each separate section, and is secured to a top of the insertion part at a lower end; the supporting tube is positioned around the connecting tube such that the annular protrusion is detained by the detaining bumps of the connecting tube, and such that it is displaceable relative to the connecting tube for adjustment of height after the annular protrusion is released from the bumps.
