1. A chuck for gripping and moving cylindrical bodies, in particular fittings and pipe segments, comprising a main body defining an axis of rotation and a plurality of jaws fastened to said main body; said jaws being movable between a position of maximum closure, in which said jaws are at the minimum distance from said axis of rotation, to a position of maximum opening, in which said jaws are at the maximum distance from said axis of rotation; said chuck further comprising a means for adjusting said positions of maximum closure and maximum opening and a means for moving said jaws between said positions of maximum closure and maximum opening; said chuck further comprising a fixing means adapted to allow the axial fixing of said chuck to a support member and the connection of said chuck to said support member so that said chuck and said support member are angularly rotatable with respect to each other, wherein each of said substantially cylindrical bodies comprises one or more hollows which are arranged parallel to said axis of rotation; the outer surface of said substantially cylindrical body having an alternating arrangement of protrusions and recesses.
