It's very difficult to render this in English properly. I would consider something as simple as "Redirect suppressors". Although somewhat cryptic, it is short and understandable.
I would not be opposed to "Movers without redirects". Although it is not very natural, it is clear and direct.
Redirect suppressors sounds more formal while "Movers without redirects" sounds more plain and sounds like "Doctors without Borders". I think either one can be used
