Abstract: The device is comprised of a part (10) susceptible of being joined to the end of the manipulator arm and which is provided with a first generally flared orifice (20) intended to receive a part which has substantially a shape corresponding to that of the article to be gripped, and a second orifice (19) extending substantially perpendicularly to the first orifice (20) and opening in the latter, as well as a rod inserted in the second orifice (19) wherein the rod is free to slide, the displacement of said rod being controlled by the manipulator so as to bear against the inserted portion of the article into the first orifice (20), in order to prevent that portion from moving.
