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.
