Ring for securing a bag to a waste container support includes an annular portion including an upper wall, an inner circumferential wall extending downward from an inner edge region of the upper wall and an outer circumferential wall extending downward from an outer edge region of the upper wall. An annular channel is defined on an underside of the annular portion. The inner and/or outer wall includes pinches each including a pair of slots extending upward from a lower edge of the wall. The slots are spaced apart from one another to enable a solid portion of the wall therebetween to temporarily flex outward, which aids in engagement and disengagement of the ring to a projection on the support, with a bag being sandwiched between the ring and projection and thereby secured to the support. Tabs may extend upward from the upper wall to aid in handling of the ring.
