What are these cable "unions" called The Moulton bike can be taken apart for travel (just using it as an example, I don't have one).  The cables that run from the handlebar to the rear triangle are not single continuous cables but are made of sections which are connected together by a sort of threaded "union" of some kind.  What are these cable-union-devices called?
Not sure if there is a tradition term for these. At the time of writing I found Some products simply called cable splitters or separators and Ritchey quick disconnectors
