An improved construction for the interengagement of the racket head portion and the handle portion of a racket is disclosed. The construction is such that the overall length of the racket can be easily varied. Additionally, the improved construction described includes a locking and unlocking feature that makes the inadvertent release or disengagement of one from the other extremely unlikely. The shank extending from the racket head includes a plurality of notches. The shank fits inside the handle and grip portion of the assembly. Exteriorly of both the handle portion and the enclosed shank lies a surrounding locking slide. A ball detent retaining means holds the slide in the locked or unlocked position in relation to the handle portion. When in the unlocked position, the handle portion and the locking slide are movable in relation to the shank, and a biased roller attached to the handle portion selectively engages the notches in the shank to allow for easy overall length adjustment.
