In a sheath,that is what the sword case is called
When putting away a sword you "sheath" it, or put it back into its sheath, usually worn on a belt or sling.
That belt is called a "sword belt" or a "scabbard belt". It is designed to secure the sheath and sword in place and make them accessible for quick drawing.

The sheath used to hold a sword is called a scabbard.
A scabbard is a sheath for holding a sword or other large blade or gun; such as a rifle. Scabbards have been made of many materials over the millennia, including leather, wood, and metals such as brass or steel.
As opposed to a sheath, a sword frog is simply a universal sheath equivalent for carrying most single-hand swords. Like a sheath, a sword frog attaches to the belt. Sword frogs are useful for those who use different swords, or do not have the time (or rarely, the money) for a custom made sheath. The name itself probably comes from the size of the sword frog, being more the size of a toad as opposed to a full sized sheath. Also it is possible that from a distance some sword frogs may have looked like frogs from a distance originally.
The use of a sword as a world wide sport is called fencing. This sport is featured in the modern Olympic games and has originated in African continent.
