ABSTRACT:
This invention relates to a device, incorporating rotating valves, for coupling pipes, wherein the control mechanism (notched discs, fingers) associated with the valves of the two elements of the device, is arranged so that rotation of said valves, during approach of the two support plates, is effected sequentially, the second valve rotating the first in order to enable the first valve to move angularly thereafter, in either case without involving displacement along the axis of the device.
