The hose is probably coiled up normally. When there is no water pressure, there is little force trying to uncoil it. When water pressure is increased in the hose, the little extra diameter from uncoiling it provides a force to do just that. Try letting the hose uncoil when under pressure. If the above is correct, then it shouldn't try to coil up when the pressure is released. Another possibility is that what you call "rings" are really a continuous spiral. I've never seen a hose with real rings, but plenty sheathed in a metal spiral. The metal is so that the hose can resist internal pressure, and the spiral is so that the metal "pipe" becomes flexible. In the case of a spiral, there can be some spring-action to keep the hose twisted, but internal pressure then acts against that to try to minimize twist.
