Abstract: A drill pipe connecting apparatus has radially extending locking openings to the drilling drive of a rig. An inner tube receives a free end of the drill pipe by the locking opening of the drill pipe. An outer tube at least partially encompasses the inner tube and connects to the drive. The inner tube has, at the drill pipe end, radially extending through-recesses for guiding/allowing passage of locking elements, radially slidingly movable in the through-recesses. External guide elements on the outer tube form control gates for adjusting the radial position of the locking elements between open/locking positions by relative rotation. A connecting device releasably connects the tubes in a rotationally fixed manner; positive-locking elements extend circumferentially around the inner face of the outer tube and on the outer face of the inner tube. These elements enter into positive-locking engagement or reach free-running position, depending upon the longitudinal tube position.
