concertina wire
Spiral barrier fencing
Concertina wire is coiled barbed wire or razor wire that expands like an accordion when deployed, forming barriers difficult to cross.
Named for its resemblance to the musical instrument when stretched, it appears atop prison fences, military perimeters, and border fortifications: The compound was ringed with concertina wire.
