摘要：
A universal joint (10) for the extension of billiard cues is disclosed, said joint comprising a joint element (12) generally tubular and adapted to hold at one end the front end of an extension and to receive at the other end the butt end of a billiard cue, and a generally tubular tightening element (14) adapted to lock the cue inside the joint element (12).The joint (10') is operative irrespective of the outer diameter of the butt terminal part of the cue received therein, by the combined action of slits (42), tapered portions (28, 38, 40) and resilience of the material of which the joint element (12) is made.
