The apparatus for connecting shaft portions of sports equipment according to claim 8, wherein said third portion of said extending member is fixedly mounted inside said second shaft portion. 10. The apparatus for connecting shaft portions of sports equipment according to claim 9, wherein said second portion of said extending member is of a cylindrical structure. 11. The apparatus for connecting shaft portions of sports equipment according to claim 9, wherein said locking means comprising a locking ring adapted to rotate about said second portion of said extending member. 12. The apparatus for connecting shaft portions of sports equipment according to claim 11, wherein said extending member comprises a locking ring positioning member adapted for restricting the movement of said locking ring from said second portion of said extending member to said first portion of said extending member, said locking ring positioning member is arranged between said first and second portions of said extending member, said locking ring positioning member is an extension which is extended outwardly from the outer wall of said extending member. 13. The apparatus for connecting shaft portions of sports equipment according to claim 12, wherein said second shaft portion comprises a second receiver member for receiving and fixedly mounting said third portion of said extending member inside said second shaft portion, a portion of said second receiver member is arranged inside said second shaft portion, a remaining portion of said second receiver member defines a sliding member adapted for allowing said locking ring to rotate on said sliding member and restricting the remaining portion of said second receiver member to be received inside said second shaft portion. 14. The apparatus for connecting shaft portions of sports equipment according to claim 12, wherein a ring-shaped structure adapted for rotating about said second portion of said extending member and restricting said locking ring to be moved towards said second shaft portion is arranged between an end of said second shaft portion and said locking ring positioning member. 15. The apparatus for connecting shaft portions of sports equipment according to claim 1, wherein said locking ring comprising first and second locking ring apertures arranged on opposing ends of said locking ring, the diameter of said second locking ring aperture is smaller than the diameter of said first locking ring aperture. 16. The apparatus for connecting shaft portions of sports equipment according to claim 1, wherein said extending member is made of a material containing nylon, carbon-fiber or metal. 17. (canceled) 18. (canceled) 19. (canceled) 20. The apparatus for connecting shaft portions of sports equipment according to claim 1, wherein said extending member further comprises a least one longitudinal element adapted for reinforcement of strength of said extending member is embedded inside said extending member. 21. (canceled) 22. The apparatus for connecting shaft portions of sports equipment according to claim 20, wherein said sliding member comprises a friction reduction layer adapted for reducing the friction between said sliding member and said locking ring when the locking ring is in rotation, said friction reduction layer is arranged on a face of said sliding member towards said second locking ring aperture. 23. The apparatus for connecting shaft portions of sports equipment according to claim 22, wherein said friction reduction layer is a coating of Teflon. 24. The apparatus for connecting shaft portions of sports equipment according to claim 1, wherein said locking means further comprises a movement restricting means adapted for restricting the rotational movement between said extending member and said first shaft portion or said first receiver means, said movement restricting means comprises at least one longitudinal concave portion arranged on an outer wall of said first portion of said extending and at least one convex structure mounted on an inner wall of said first receiver means or said first shaft portion, said longitudinal concave portion is an open-ended hole extending along the length of said first portion, said convex structure is a longitudinal convex structure mounted along the inner wall of said first receiver means or a portion of inner wall of said first shaft portion. 25.
