A double ended chuck, connector or shaft coupling includes a pair of back-to-back key operated chucks having a common main body upon which one set of oppositely disposed inclined jaws extends beyond and moves in the spaces between the jaws of the opposite set. The ring gears at each end are split for radial insertion behind the respective end heads and are held in place by split covers in turn held in place by a cylindrical shell sleeved thereover.
