An article holding tray assembly is for use on a ladder having elongated side pieces and lower and upper open-ended rungs joining the side pieces. The assembly includes a tray member, a backing member connected to the tray member along a straight line, a lower tubular member parallel to the line and projecting in a predetermined direction from the tray member to a free end, an upper tubular member parallel to the line and projecting in the predetermined direction from the backing member to a free end. The tubular members are adapted for insertion, free ends first, into the lower and upper rungs, with the tray and backing members substantially mutually at right angles. The tray assembly also has a resilient clip member with a body portion capable of flexure and projecting in the predetermined direction from the backing member, a locking portion integral with the body portion and providing a locking surface spaced a predetermined distance from the backing member and facing in the direction opposite the predetermined direction, and a cam portion integral with the locking portion and providing a cam surface integral with the locking surface at its edge remote from the body portion and positioned to be engaged by the rear edge of a ladder side piece, thereby to flex the body portion to permit the locking portion to traverse the rear of the side piece and then snap forward to overlap the same.
