The invention relates to a support for holding open a bag, in particular a plastic material rubbish bag. The support comprises a hoop and a plurality of clips spaced equidistantly around the hoop. The hoop defines an opening through which the open bag may be inserted with the opening of the bag being clipped to the clips. The hoop thereby supports the bag so that the bag hangs through the opening when the hoop is raised. The hoop has a circular cross-section, with each clip being spring-biased to conform to the hoop, so that the bag is pinched between the clip and the hoop. When the bag hangs from the support, the weight of the bag bears on each clip to pinch the bag tighter in each clip.

A support as claimed in claim 1, in which said convexly curved portion faces away from the hoop opening. 3. A support as claimed in claim 1, in which said convexly curved portion faces in towards the hoop opening. 4. A support as claimed in claim 1, in which the hoop has a substantially circular cross-section. 5. A support as claimed in claim 1, in which forces between the bag opening and the hoop are essentially normal to said convex surface of the hoop and clip where these contact the bag opening in order to retain the bag opening to the hoop. 6. A support as claimed in claim 1, in which the convex surface extends substantially fully around a cross-section through the hoop. 7. A support as claimed in claim 1, in which the surface and the clips extend over an arc of up to about 270°. 8. A support as claimed in claim 1, in which the clips have a lip that rises from the surface of the hoop to aid insertion of the bag between the clip and convex surface of the hoop. 9. A bag support assembly, comprising an open bag and a bag support which supports the bag, in which the bag support comprises a hoop and a plurality of clips around the hoop, the hoop defining an opening through which an open bag may be inserted with the opening of the bag being clipped to the clips, the hoop thereby supporting the bag so that the bag hangs from the hoop opening when the hoop is raised, in which: the hoop has an outer surface with a convexly curved portion and each clip is permanently held to the hoop with a free portion of the clip that has a spring-biased shape that conforms with said convex surface over an arc of at least about 90°, each clip terminating at a free end that may be pulled away from the convex surface to allow a bag opening to the inserted between the clip and the hoop wherein the clip is hinged so that the free end of the clip can be retracted fully from the hoop. 10. A bag support assembly as claimed in claim 9, in which the hoop and/or the clip is roughened to improve grip on the bag. 11. A bag support assembly as claimed in claim 9, in which the hoop and/or the clip has an elastomeric surface to improve grip on the bag.
