ABSTRACT:
A connection device for connecting a tubular member to another member comprises a clamp ring, which is arranged in an inner bore of an outer housing, and includes a plurality of clamping fingers which are deflectable essentially in radial direction relative to the inner bore and a deflecting bushing which is displaceable by at least one driving means in axial direction of the inner bore between a stand-by position and a deflecting position. The deflecting bushing in its deflecting position deflects the clamping fingers radially inwardly. The driving means comprises a rotatable, axially not displaceable spindle along which the deflecting bushing is movable.
