Zusammenfassung:	A plastics collar for retaining a plug lid (45) in a ring (44) double seamed to can body (1), has a peripheral skirt (38) portion having on its interior surface a snap fit bead (41) for entering under the double seam (3); a planar annulus (37) extending radially inwards from the top of the skirt over the seam (3) and at least part of the ring (44) and lid (45); and an annular rib (43) extending down from the planar annulus to hold the lid in the ring. The collar may be provided with a jacking screw (39) to assist removal from interlock with the double seam (3) and progressive removal is facilitated by a radial slit or line of weakness (42) at which the collar first parts from the can.
