Abstract: A shrink ring clamp assembly for securing together a pair of telescoped pipes comprises opposed die holders within which are secured opposed coplanar semi-circular shrink ring die segments, so that when the die holders and segments are compressively drawn together relative to a pair of telescoped pipes, concentric annular channels and a bead are formed therein providing an annular mechanical interlock and seal between the pipes. The method of securing the pipes together including the step of forcefully drawing together a pair of coplanar shrink ring die segments relative to a pair of telescoped pipes therebetween to form concentric channels and a bead therebetween providing an annular mechanical interlocking seal throughout 360.degree..
