ABSTRACT OF THE DISCLOSURE A pipe repair sleeve and liner with interlocking elements in a form of a coiled sheet which is covered with compressible gasket. An air bag is inserted into the coiled sleeve and moved to the location of the damaged pipe. Once in place, the air bag is inflated. As a result of the inflation, the repair sleeve uncoils and the surrounding gasket is compressed against the damaged pipe. When the air bag is deflated, the sleeve begins to coil and forces a male end of the sleeve into the female end forming a male and female interlocking continuous sleeve inside the pipe. After the repair sleeve is installed in the pipe, the air bag is removed from the sleeve.
