Abstract
An ostomy bag with a wall of a flexible material and a first coupling member for detachably coupling the ostomy bag with an implant, for example an implant surrounding the stoma, with the first coupling member being and designed with a circumferential groove. The first coupling member is a spring ring composed of a spring wire having end parts extending a distance past each other. Along the opening of the ostomy bag, an edge reinforcement is made by joining of at least a part of the spring ring and an area of the wall of the ostomy bag, and on each end part of the spring wire is a handle for opening the spring ring on overcoming the spring power in the spring ring so that the edge reinforcement can pass over the circumferential groove of the implant at mounting and decoupling of the ostomy bag.
