<p>The nut (1) has an internal thread, and a detachable ring element (2) including sawtooth inner teeth working together with sawtooth outer teeth, and contact surfaces for transmitting force for picking up and releasing the nut. A connection between the ring element and the nut is rotatably fixed in a rotational direction, and is limited in an opposite rotational direction by limit torque. A latching connection is arranged between the ring element and the nut. The ring element is fixed perpendicular to the rotational direction to the nut by the latching connection.</p> |
