Dispositif de raccordement d'éléments tubulaires

摘要

A device for connecting tubular elements, especially fragile elements such as glass tubes, utilizing two interconnected half collars that permit relative rotation. An elastic and chemically inert joint comprising an elastomer core and an envelope of polytetrafluoroethylene is positioned between the tubular elements. The half collars may be interconnected by a male-female arrangement on bosses and a ferrule.
