I don't know. I haven't seen the hose and the connector, so I can't say what it might or might not be doing. Are you sure the hose would be just as secure without it? Again, if there is no change in cross section, I don't see how it can impede the flow. Have you seen it? Is there really no reduction of the diameter throughout the connector? Well, I guess the connector wall might have a different surface finish than the finish of the hose, but that should be an insignificant effect. Another possibility is that the hose might need to have some slack in it to meet some spec, and they don't want to manufacture a specific hose for the M3, and the are using the dummy connector--if that is indeed what it is--not to strain the hose. Many possibilities...
