ABSTRACT:
The invention relates to a coupling element which can be coupled to a lifting element of an object to be lifted. The coupling element is provided with a remote-controllable locking element, which in a locking position is designed to prevent disconnection of the coupling element and the lifting element connected thereto. A rotatable driving element, which is in engagement with the locking element, is fitted in the inside of the coupling element. The rotatable driving element by means of a control element can take the locking element into or out of the locking position.
