Abstract: A holder for a waste-disposal bag, to be installed in a confined space such as the interior of a passenger automobile, has a mounting bracket secured to an upright wall to which a rectangular frame is articulated for swinging about a horizontal pivotal axis from a depending position into a level position in which it is arrested by a stop. A lid overlying the frame is biased by a torsion spring into a closure position and has an edge portion projecting beyond the frame engageable by a user's finger for swinging the frame from its depending position into its level position and, thereupon, lifting the lid off the frame in the same motion to give access to a bag suspended from a rectangular insert inside the frame. The insert, which like the frame and its lid consists of plastic material, is resiliently indexed in the frame and rests against internal abutments thereof which are integral with a ledge forming an abutment for the torsion spring.
