<p>This invention relates to an improved locking device in a joint for a sporting implement derived from at least two separable elements, one of which telescopes into the other along a common axis in sliding fit to provide a region of overlap, In particular the two separable elements of the sports implement include a handle or shaft portion and a blade or head portion. One of these portions presents a projection formation to a receptacle formation presented by the other of such portions. A displaceable locking member comprising a boss having a flanged part and projecting part is carried by one of such formations and is operably displaced so that the projecting part extends in full registration within an aperture or recess provided in the other of such formations. In an alternative embodiment a bias is provided to normally urge the displaceable locking member within engagement or registration in the aperture or recess so as to releasably secure the handle or shaft portion against separation from the head or blade portion.</p> |
