摘要：<p>The present invention relates to a coupling for ducts, in particular for gas, having two end pieces, each provided at one of their ends with a connecting end piece. The coupling comprises a ring (4) holding the two end pieces in the extension of each other on a same axis in a first fitting stage. It comprises a special seal (3) and two half-shells (6, 7) to be employed in a second fitting stage in order to ensure longitudinal locking. Application to an ultra-high vacuum or high-pressure coupling. <IMAGE></p>
