Abstract
A locking mechanism for fixing an outer part (5) on an inner part (4) having locking members (8) which are guided in apertures (7) of the outer part so as to be radially movable in a limited way. In the locking position, these locking members (8) are supported radially outwardly on a locking ring (10). A control ring (16) retains the locking ring in the open position. For this purpose, the control ring (16) is displaced eccentrically and is supported on a stop (19) associated with the outer part (5). By inserting the inner part (4), the control ring (16) is aligned coaxially by the control members (8) so that a spring (12) loading the locking ring (10) can act to move the control ring (16) across the stop (19) so that the locking position is achieved.
