Minor Upper radiator hose problem

[Sean486]

After replacing the upper radiator hose, I am having some problems with it wanting to slip off. When I replaced it, one of the original clamps had to be replaced, and was replaced with a generic radiator clamp. Seems like when it is tightened it makes the hose want to pull away. Anyhow, I thought I had it on pretty good, but after checking it a few weeks later it looks like it has slipped down again, and is almost ready to come off. Is there anything I should put on the end so that it stays in place better, or do I just need to get a new Subaru type clamp for it?
