Abstract

There is provided a spring comprised of a wire which includes an elastic, coiled central portion and opposing end portions formed as hooks. Each hook terminates in an end having a hole therethrough. The spring is useful with an exhaust system of the type having a pair of sections joined but not affixed to one another to thereby form a flexible joint. A loop is fixedly connected to each section adjacent to the joint. The opposing hooks of the spring are securely received by the loops, and a safety wire is received through the hole in the end of each hook and secured to the corresponding loop. In an aircraft having an exposed exhaust system, the safety wire prevents a broken spring or loop from impacting and damaging vital components of the aircraft, particularly a pusher propeller positioned to the rear of the exhaust system.
