The collecting bag has a bag member (2) formed by a first and a second film blank (2, 3) , and a discharge portion (8) that is foldable and unfoldable to bring the discharge portion from an open unfolded condition to a closed folded condition and vice versa. A first plate member (21) is positioned on the first film blank (2) and a second plate member (22) is posi~tioned on an extension (3a) of the second film blank (3) . A locking device is provided at the discharge portion for locking the bag in the closed folded condition of the discharge portion. Each plate member (21,22) is formed from a relatively stiff material, and the distance (d) between the distal edge (21b) of the first plate member (21) and the proximal edge (22a) of the second plate member (22) is smaller than the thickness of the first plate member.
