@vi Definitely not "Du bras" XD

Maybe something like "Brassort", which is completely ridiculous (so maybe not) but it's a combination of "bras" + "ressort" (spring).
Titles in French are either short sentences, nominal groups, or a maked-up noun (what I tried, and failed, to do with "brassort"), usually not a common noun by itself like "bras", I guess.

But yeah, when it's a common name it's usually with "le/la/l'" before. So you could have a book named "l'arbre" for example (but it would usually be "l'arbre tricentenaire" -> nominal group, or "l'arbre que j'ai planté" -> short sentence). In this case "les bras" could work. But it sounds stupid.
