Abstract
A coupling device includes a polygonal coupling part on one of the parts to be coupled for engaging a complementary polygonal counterpart on another of the parts to be coupled. The polygonal coupling part has outer side faces, a longitudinal bore therein, and a first transverse bore with a ball therein intersecting the longitudinal bore and one of the side faces. An actuating body tapering at first and second ends is guided for longitudinal movement in the longitudinal bore between an extended position wherein the first end moves the ball radially into a locking position and a retracted position permitting inward movement of the ball out of its locking position. A second transverse bore intersecting the longitudinal bore guides a releasing element having a cam surface engaging the second end of the actuating body. The releasing element is movable against the action of a biasing spring to move the actuating body from its extended position to its retracted position.
