ABSTRACT:
A device for closing, connecting and/or locking including a driving element and a driven element having a threaded end. The driven element is at least partially positioned within the driving element. An axial anchoring structure axially anchors the driving element to the driven element while allowing rotation of the driving element and the driven element. A rotational anchoring structure anchors the driving element to the driven element for unitary rotation in a first rotation direction, only up to a limited tightening torque. The rotational anchoring structure allows the free rotation of the driving element in a second rotation direction opposite to the first rotation direction. A locking structure locks the driving element with driven element for unitary rotation in the second rotation direction.
