An openable securing ring for holding a lid 16 or similar closure on a container 14 has a latch mechanism 22 arranged to secure ends of the ring releasably together at a circumferential break. A circumferentially extending recess 30 is provided at a radially inner portion of the latch mechanism so that the radially inner portion is of reduced axial external thickness and provides relief for stable stacking of a first container 12 on top of a second container 14 when the securing ring is attached to the second container. A radially inner edge of a locking lever side wall 24 may lie radially outward of the inner diameter of one ring end 28 to define at least part of the reduced thickness radially inner portion. |
