Abstract: A quick-coupling connector, particularly for pipes of climate-control, refrigeration and similar systems, comprising a first connector portion adapted to be connected to an end of a male pipe and a second connector portion adapted to be connected to an end of a female portion, the first and second connector portions being adapted to be connected to each other, at least one elastomeric element being interposed between the end of the male pipe and the end of the female portion when the male pipe and the female portion are connected one inside the other.

Abstract: A device for reducing the permeability of tubing in climate control, air conditioning and refrigeration systems, comprising elements for recovering gas escaped by permeation from at least one tube that is at a first temperature and pressure, adapted to convey the permeated gas to a region of the system that is at a second temperature and pressure, the second pressure being lower than the first pressure.
