Abstract
A pneumatic screw driving device includes a body having a grip to be held by an operator and housing a pneumatic motor, a rotating terminal member for cooperating with a screw driving element and liable to be driven in rotation by the motor, and a coupling piece for an air feed tube for supplying air to the motor. The coupling piece includes a first element partly mounted inside the grip, and a second element external to the grip for being connected to the air feed tube. The second element is fixedly attached to the first element by a rotating link. The first element and the second element are mobile relative to each other.
