Abstract
A device for locking a cover on a container body, particularly a wheeled barrel, having a locking piece mounted to pivot between a position assuring the locking of the cover in the closed position on the body and an unlocking position releasing the cover, and an operating member cooperating with the locking piece to bring the locking piece to an unlocking position for a predetermined inclined position of the container. The operating member is a movable weight (13) mounted for guided sliding movement, and the locking piece (11) and the operating member (13) comprise cooperating projecting means (24, 23) arranged so that a translatory movement in one direction (20) of the operating member produces a rotation of the locking piece (11) in the unlocking direction (21).
