A gripping apparatus includes an inner sleeve having an outer surface and an inner bore. The inner sleeve defines at least one radial opening that extends from the outer surface to the inner bore. The inner sleeve is at least partly received within the interior space of an outer sleeve. At least one rolling locking element is positioned within the at least one radial opening of the inner sleeve. The inner surface of the outer sleeve is shaped so that rotation of the outer sleeve relative to the inner sleeve drives the at least one rolling locking element radially inwardly into the inner bore of the inner sleeve, and axial movement of the outer sleeve relative to the inner sleeve in an axial direction opposite drives the at least one rolling locking element radially inwardly into the inner bore of the inner sleeve.
A gripping apparatus having a first end and a second end that is spaced from the first end along a central axis in a first axial direction, the gripping apparatus comprising:
