An apparatus used with a sleeve style receptacle to make an animal waste bag holder apparatus. The apparatus includes a cylindrical sleeve, a holder configured to temporarily hold a plastic bag inside the sleeve that includes a bolt that extends through a hole formed on the sleeve, a lock washer that attaches to the shaft to hold the shaft inside the side hole, a flange nut with internal threads that selectively attaches to the end of the shaft configured to press against the outside surface of the cylindrical sleeve. During use, a bag is inserted into the sleeve so the top edge of the bag fold over the sleeve and positioned adjacent to the hole. When the flange nut is tightened on the shaft, it eventually presses against the portion of the bag adjacent to the side hole. When further tightened, the flange nut pulls the portion of the bag around the shaft causing it to tighten around the sleeve.
