Abstract: A bag holder has a hollow body 1 of truncated-conical form open at both top 3 and bottom 4. A truncated-conical ring 2 inserted through the top 3 of the body 1 engages in the mouth 21 of a bag 20 entered through the bottom 4, and is pushed down into the body 1 to wedge against the inside of the body-wall 5, and thereby retain the bag 20 in the holder with its mouth 21 open. The body 1 and ring 2, both molded of plastics in one-piece, are of conforming D-shape transverse cross-section, and a flat tongue 7 projects above the open top 3 as an extension of the flat part 6 of the wall 5. Hand-grips 9 for lifting, project above the top 3 from the outside of the wall 5, and lugs 10 either side of the grips 9 project outwardly from the body 1 to limit the depth of its stacked-insertion within a similar holder.
