ABSTRACT:
A golf club which includes an adjustable shaft, in which the shaft comprises an inner shaft part, an outer shaft part which receives an end of the inner shaft within it in a telescoping arrangement, and an internal tube which is fastened within the outer shaft part and which extends along the inside of the outer shaft to engage the inner shaft part in a telescoping arrangement. One of the internal tube and the inner shaft part is split at its end. The club includes a locking mechanism by which the inner shaft and the internal tube can be locked together against relative axial and rotational movement, comprising an expander which can be withdrawn into the split end to cause it to become splayed, to engage the internal surface of the other of the internal tube and the inner shaft part. The expander can be withdrawn into the split end to cause its end to become splayed by the action of a resiliently deformable spring, which biasses the expander towards the locking position.
