Abstract A cover-closure for containers having a relatively large opening, in particular for barrels, cans or the like, produced of synthetic material, which comprises a container having on the outside at its edge an annular rim formed of the container wall and radially projecting locking cams. A cover has an edge disposed downwardly angularly and outwardly surrounding the annular rim in the securing position. The segment is divided at least partly into segments equipped with projections extending outwardly from the lower end section, by means of vertical cutouts. The segments, in case the cover is mounted, is capable of being tensioned against the container edge below the annular rim with a tensioning ring disposed on the outside about the segments and capable of being locked below the locking cams. The container has at least three of the locking cams formed of the annular rim and is along the periphery symmetrically disposed and formed of the annular rim. In the container-wall sections are disposed between the locking cams below the locking cams at least one deepening provided adjusted as to shape to the cover edge segments.
