ABSTRACT:
A coupling for inner and outer telescoping shafts comprises a one-piece sheetmetal clip having a sleeve portion slidably received on the outer shaft. A resilient leg portion extends longitudinally from the sleeve portion and is provided at its free end with an inwardly projecting locking hub and an outwardly projecting internally threaded collar. In its collapsed retained mode the locking hub extends through an aperture in the outer tubular shaft and flexes the leg portion biasing the inner shaft into frictional retained engagement with the outer shaft. Upon the shafts being axially moved to an extended locked mode the hub is snapped into an inner shaft blind bore. This aligns an inner shaft through bore with opposed holes in the outer shaft and the collar for threaded reception of a through bolt.
