ABSTRACT:
A locking device, especially for a cover (11) of a suction cleaner, comprises at least one movable latch (12) cooperating with a corresponding step (13) on the cover. The latch is attached to the free end of a leaf spring (14). A control means (17) is provided adjacent the leaf spring and movable in parallel therewith. The control means has a push button (17a) at one end and an inclined guide surface (17b) at its other end, said guide surface cooperating with a corresponding stationary supporting surface (18). Axial displacement of the control means (17) by means of the push button (17a) results in a lateral movement which actuates the leaf spring (14) to release the latch (12) from its engagement with the step (13).
