ABSTRACT:
A locking device (1) for use with joints between two telescoping members (28,30) include a bushing (2) with an enlarged head (8) and a neck (6) for inserting into a pair of aligned holes (34) in the telescoping members (28,30). The device is locked by drawing a bolt (16) into the central bore (10) of the bushing (2) by drawing means (20,22,24). The bolt (16) includes a lug (18) for contacting the inner telescoping member (28). Also provided is a channel (14) in the neck (6) which permits the lug (18) to slide within the bushing (2), thus allowing effective engagement of the device (1) for a range of telescoping member wall thicknesses.
