Drawing a ridge around a loft

Hi.

I am drawing a simple pourer. It is oval at one end and smaller diameter round at the other. The idea is it is pushed into a hole like a hollow cork. It also has a curve along it's length.

I used a loft to create the pourer 

What I want to do is to put a ridge around the circumference of this loft some way back from one end. It will be a triangular ridge as a barb to hold the pourer in the hole. I can't for the life of me work out how to get a shape to follow around the circumference of the loft, which is not perfectly round as it blends from an oval to a circle. I thought the sweep extrude was the key, but I can't constrain the triangle sketch to the surface of the loft, nor select the loft surface as the sweep path. Am I trying to do the impossible?

If the ridge is planar, create a plane and split the face using the plane - that will create a path that you can use to sweep a sketched circle.

It's not entirely clear what you are trying to do - please post a link and some pics

This is my drawing.

I would like to build a ridge around the spout where I have drawn a red line. 
Does this make sense?

Thank you Neil. I figured it out. I also worked out how merge all can rejoin the split, so I end up with one part again.
