Claim:
Device for conveying and/or distributing fluids, comprising: a housing with a tightening seat and one or more tubular connection portions that are removably connectable with corresponding connection portions of a fluid conveyance and/or distribution system, one or more threaded ring nuts adapted to be screwed to said connection portions, said ring nut having an engagement portion which forms a ring gear, one or more fastening rings adapted to be screwed into the tubular connection portion to ensure the positioning of internal components of the device, and a first adapter comprising: A) a valve coupling portion adapted to be supported by the tightening seat in a tightening position allowing rotation of the first adapter with respect to the housing around a tightening axis, B) a drive portion which forms a toothed section, wherein, when the first adapter is supported by the tightening seat in the tightening position and the ring nut is at least partially screwed on the connection portion, the toothed section of the first adapter engages with the ring gear of the ring nut and a rotation of the first adapter with respect to the housing around the tightening axis causes a screwing or unscrewing of the ring nut, depending on the first adapter rotation direction, C) a first key seat for coupling of a tightening tool for rotating the first adapter in the tightening position with respect to the housing around the tightening axis, and a second adapter comprising: D) a mounting portion adapted to torsionally engage a tool seat of the fastening ring, E) a second key seat for coupling of the tightening tool for rotating the second adapter.
