ABSTRACT:
An enclosure to define a substantially annular chamber around a conduit to be tested for leakage, and to confine a liquid to permit the visual detection of gas bubbles indicative of a gas leak in the conduit. The enclosure is sleeve-like and includes two body members pivotable about a longitudinal hinge to permit quick attachment to and removal from a pipe section. A longitudinal seal is provided and a radial seal extends from corresponding ends of the body members to define the bottom wall of the enclosure and to sealingly engage the pipe.
