A releasable coupling for connecting a first and a second component to one another, includes a first sleeve-like hollow member affixed to an end of the first component and a second sleeve-like hollow member affixed to an end of the second component, an expander mandrel supported in the first hollow member and arranged for an axial motion with respect to the first hollow member to assume an advanced position in which it projects into the second hollow member to be surrounded simultaneously by the first and second hollow members. The expander mandrel includes an expander element and pressing elements operatively connected to the expander element for displacement generally radially outwardly by the expander element into an expanded position for a simultaneous engagement with the first and second hollow elements thereby clamping the first and second components to one another. There is further provided a power device for axially displacing the expander mandrel as a whole and for displacing the expander element relative to the pressing elements. Each pressing element has a toothed outer face and each hollow member has a toothed inner face. In the advanced position of the expander mandrel and in the expanded position of the pressing elements each toothed outer face is in a meshing engagement with both toothed inner faces. |
