An arrangement for connecting fecal receiving bags together provides for a simple coupling arrangement, which provides fluid communication between the bags while preventing odor and fluid to leak from the coupling. Such a coupling arrangement between two receiving devices or bags is discreet and comfortable to wear as the coupling members follow the extent of the receiving devices. The coupling members are furthermore capable of extending parallel to the first and second plane of the receiving devices and thereby reduce the extent to which the coupling members bulge out. A method for connecting fecal receiving bags into a coupling arrangement employs the coupling members.
