ABSTRACT:
Attachment means for connecting an insulated pipe to an element, such as the manifold, in the exhaust system of a vehicle. The attachment means includes a conduit which extends into the end of the insulated pipe. A transverse lug or a helical flange on the conduit engages the spiral corrugations of the inner diameter of the pipe to allow the conduit to be threaded into the pipe. The end of the pipe is received in an end cap slidably mounted on the conduit. When the cap hits a stop on the conduit during threading of the conduit into the pipe the lug or helical flange pulls the pipe against the cap, tightening the connection to the pipe.
