It means- The sleeve
La Manche means "the sleeve" in French. It is called that because it looks similar to a sleeve, Wide in one side (between the cities of Brest, France and Plymouth, UK) and narrow at the opposite side ( between Calais, France and Dover, UK).
It literally means 'the sleeve'. But, it refers to the English Channel.
