Abstract
Improved tube spanner for nuts, characterized in that a circular groove, of adequate depth to receive a nut retention ring, is provided inside the key; said key is integral to a tubular shaft equipped with the corresponding handle, through which axially slides a rod provided with a piston that rests on the bottom of the key, while at the opposite end involves a button that protrudes from the end of the handle, requested by the action of a spring antagonist to the direction of advance of the rod, so that overcoming the tension of said spring, the piston comes in contact with a nut trapped in the retaining ring to release it from its action.
