Date Jul. 4, 1996A collecting bag system for human body wastes comprises a collecting bag with a bag element formed by two predominantly oblong plastic film blanks with joined edges and with an inlet opening surrounded by connecting elements for connection to a body orifice, particularly a stoma, and a closeable outlet opening in an end section of one plastic film blank. The outlet opening is surrounded by a coupling ring with an outwardly facing engagement flange, and the system further comprises a bag extension with a coupling ring with a corresponding inward-facing engagement element for dismountable, sealing coupling to the coupling ring of the outlet opening. On the inside of the coupling ring of the outlet opening a closing membrane is placed with an annular coupling element for a sealing, but releasable coupling with an inward-facing engagement element on the coupling ring of the outlet coupling.
