Abstract
Abstract A process for joining together connecting parts of at least two containers which contain fluids at identical or different pressures, in an ambient fluid with a pressure that is lower than that of at least one of the containers, while preventing the ambient fluid to be introduced into one container, comprising the steps of first liberating the fluid of the container with a pressure higher than that of the ambient fluid, while effecting coupling of the connecting parts, and subsequently driving out the ambient fluid from the empty spaces between the connecting parts.
