A connection assembly for an exhaust extraction system which is designed to vent the exhaust from a vehicle tail pipe includes, in combination, three primary components. The first component is an annular sleeve which is constructed and arranged to assemble onto the vehicle tail pipe. A band clamp is used for this connection in order to establish a leak-free interface. Next, there is a nozzle locator ring which slides onto the annular sleeve such that one end of the sleeve extends beyond one side of the nozzle locator ring and the opposite end of the sleeve extends beyond the opposite side of the nozzle locator ring. There is an offset portion intermediate the ends of the annular sleeve which serves as an abutment for the nozzle locator ring. The third major component of the connection assembly is an exhaust nozzle assembly which includes, as its primary components, a generally cylindrical nozzle constructed of a thick walled synthetic material designed for moderate flexibility and a pair of magnet packs located circumferentially 180 degrees apart. The exhaust nozzle assembly is designed to slide onto and fit up against the nozzle locator ring. Once the nozzle is securely seated, the two magnet packs are in position to contact the outer surface of the annular sleeve. Each magnet pack is designed with pole pieces which sandwich a plurality of magnets therebetween and the pole pieces are able to pivot which facilitates the assembly as well as the disassembly of the exhaust nozzle assembly relative to the nozzle locator ring.
