A male/female billiard cue connector provides multi-directional vibration damping as well as accurate alignment of the cue's handle and shaft. The strike of the cue against the cue ball causes a longitudinal shock wave to traverse the length of the cue generating strong transient forces within the cue. Due to the rigidity of the cue, this longitudinal wave also excites lateral vibrations in the structure which cause the cue to bend and flex, and the resultant forces wear and abrade the connector elements. The connector provides protection against these forces, as well as assuring true axial alignment of the cue. The male section of the connector, fitting into a cavity in the female section, has two circumferential rubber "O" rings that are in contact with the walls of the female connector when the male and female sections are joined. These "O" rings absorb and dissipate the energy of the lateral vibrations induced in the cue. Additionally, the male section screws onto the threaded end of a spring loaded axially "floating" plug in the female cavity, to provide accurate axial alignment of the connector parts, while allowing a slight axial movement between them. Sandwiched between the male and female sections is a resilient mechanically dissipative disk that cushions the relative axial movement of the connector parts during the strike impulse, and absorbs the longitudinal shock wave.
