Patent abstract
A coupling device for a fluid line has a collet and an axially movable actuating sleeve serving for operation of the collet. The collet bears several gripping teeth with associated actuating portions able to be acted on by actuating faces on the actuating sleeve in order to hold the inserted fluid line. In the non-operated state of the actuating sleeve there are at least partly different distances between the mutually associated actuating portions and actuating faces so that on actuation of the actuating sleeve several actuating portions of the collet are acted on one after the other. This means that the necessary actuating force is reduced.
