Abstract:
1. A device for closing, connecting and/or locking comprising: a driving element; a driven element comprising a threaded end, wherein the driven element is positioned at least partially within the driving element; axial anchoring means for axially anchoring the driving element to the driven element while allowing rotation of the driving element and the driven element; rotational anchoring means for anchoring 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 means allowing the free rotation of the driving element in a second rotation direction opposite to the first rotation direction; and locking means for locking the driving element with driven element for unitary rotation in the second rotation direction, wherein the locking means comprise a key which simultaneously engages the driving element and the driven element in a specific position of the driving element relative to the driven element, fixedly connecting the driving element to the driven element during rotation in the second rotation direction, and wherein the key comprises a thin, profiled, high resistance blade to be inserted in a complementary-shaped seat of the driving element and into a gauged seat of the driven element.
