ABSTRACT:
A connecting assembly includes a first tube having an oval inner periphery with a boss extending from an outer periphery thereof, a second tube having a circular outer periphery and a sleeve connected the first and the second tube together. The sleeve has an inner tube which connects to two end plates extending radially and inwardly from one of two ends thereof so as to define a cylindrical recess between the sleeve and the inner tube. The inner tube has an oval outer periphery and two slots defined diametrically opposite therein. The sleeve has a transverse opening defined therein and which communicates with one of the two slots. A longitudinal recess is defined in an inner periphery of the sleeve and which communicates with the transverse opening so that the second tube and the first tube are firmly and respectively received in the inner tube and the tubular recess by rotating the sleeve.
