A connecting unit (1) for detachable mounting to the tip of a crane boom in order to form a connection between the crane boom and an associated crane implement (4). The connecting unit comprises:- an insertion part (10) to be inserted into a hollow crane boom section;- a holding part (11), which is fixed to the insertion part and forms a support for the crane implement;- one or more supporting elements (12a, 12b), each of which being moveable transversely to the longitudinal axis of the insertion part in order to allow the supporting element to be pushed outwards in relation to the longitudinal axis of the insertion part and against an inner surface of said crane boom section and thereby take up a play between the insertion part and the crane boom section; and- an actuating device for moving the supporting elements transversely to the longitudinal axis of the insertion part.
