Abstract
A coupling device for releasable and sealing connection to a tubular, externally threaded connector part. The device includes internally threaded segments which can swing radially to enable the coupling device to be connected to and released from the connector part. An axially movable sleeve is mounted concentrically around the segments and can be moved over the segments between a forward position in which the sleeve brings the threaded segments into meshing engagement with the threads of the connector part, and a rear position in which the segments are able to swing out so as to release the engagement. The segments and the sleeve also include mutually coacting means which, when in engagement with one another, limit the possibility of relative rotational movement in one direction between the segments and the sleeve.
