A hanging element (1) for commodity display has a joining slot (12) for inserting the right end (5a) of the mounting hole (5) of the hook formed on the opening paper (2), a joining slot (11) for inserting the left end (5b) of the mounting hole. The joining slot (12) has a guiding part (15) and a inserting part (16) branching down from the guiding part, a returning part (19) is formed on the entrance (16a) of the inserting part (16). A bending part is formed in the most inside of the guiding part (15) directing towards the returning part (19). The left end (5b) of the mounting hole moves down along the inclined plane part (11b), the opening paper (2) moves to the left side, when drawing the commodity. Companying with this action, the right end (5a) of the mounting hole enters into the bending part (20), the opening paper (2) is locked by the returning part (19). Hereby, the right end (5a) of the mounting hole is difficult to enter into the inserting part (16), capable of preventing thehanging element (1) shedding from the opening paper (2).
