ABSTRACT:
Apparatus for use in remotely connecting a plurality of lines for carrying fluid terminating in a first hub to a plurality of lines for carrying fluid terminating in a second hub, the hubs being initially arranged with their axes approximately coaxial but spaced apart, comprises a plurality of first engagement members fixed relative to the first hub and comprising generally conical receptor elements forming end portions of elongate tubular members arranged around the first hub with their axes generally parallel to that of the first hub, and a plurality of second engagement members comprising generally conical elements forming end portions of elongate members arranged around the second hub with their axes generally parallel to that of the second hub. The second engagement members are slidably received in guide sleeves fixed to the second hub, the engagement members being movable relative to the guide sleeves between extended positions in which the conical elements are received in and engage the conical receptors to axially align the hubs, and retracted positions. Latch means are mounted on the second engagement members for latching the first and second engagement members together when engaged so that retraction of the second engagement members will juxtapose the hubs.
The apparatus also includes clamp means for clamping the juxtaposed ends of the hubs together. A seal plate carrying seals for sealing the connections of the fluid lines in the hubs may be inteposed between the end connection faces of the hubs before they are clamped together.
