A device (100) for arrangement on the side wall of an intestine is provided. The device (100) comprises a first member (10) and a second member (20) of a generally hollow open configuration. The first member (10) comprises an elastic part (11), with a first and a second axial end, and a rigid support part (12), arranged at the first axial end of the elastic part (11). The second member (20) comprises a first and a second axial end, said first end of the second member (20) matching the shape of the second axial end of the elastic part (11), such that an intestine wall may be uniformly distributed between the second axial end of the elastic part (11) and the second member (20). The device (100) also comprises a connection member (30) for connecting the rigid support part (12) and the second member (20) to each other. A method for arranging said device at the side wall of a tubular structure, and a connector (200) for connecting two devices (100) is also provided.
