Abstract
Two joint components in a pipe conduit are secured together in seal-tight fashion by means of rotatably mounted dogs in one of the joint components which are rotated via individual slides into an active locking position. The slides are, in turn, activated from a common pressure source. In addition, a wedge is positioned in the joint component under a housing in which a dog is rotatably mounted so as to be slid radially inward by a slide after the dog has been rotated into a locking position. In one embodiment, a double acting piston and cylinder arrangement is used for actuating the respective slides.
