A lock ring for securing a lid to a drum-type container has a body with a discontinuous ring shape and first and second free ends. The body has an annular wall and two spaced apart flanges defining a clamping channel facing radially inward. A lever has a grip section and a pivot section at opposite ends. The pivot section is pivotally attached to the body near the first free end. The lever is pivotable between a closed position and an open position and has two walls spaced from one another and connected by a third wall. A lever end is adjacent the first free end and is formed by the annular wall and one flange of the two flanges continuing to the first free end and the other flange of the two flanges terminating short of the first free end. When the lever is in the closed position, the third wall of the lever lies adjacent the annular wall, the annular wall of the lever end is positioned between the two walls of the lever, the body is captured between the two walls of the lever along the grip section, and a portion of one wall of the two walls of the lever lies generally in the same plane as the other flange along the lever end. |
