Those are called snap ring, retaining ring, or lock ring pliers. They are found in numerous machines like vehicle transmissions. The pair he is holding looks to be a USAG branded one; which is an Italian tool manufacturer. You can get them with serrations for extra grip and/or dimples for a positive lock on the ring. They always open outward and always have a spring.
