Abstract
A flexible joint, especially adapted for pipes in an exhaust system of an engine is disclosed. A locking ring is disposed over a flared end of the first pipe and a stop flange and a slidable locking flange are provided on the second pipe with a wave spring disposed between them. A sealing ring having a spherical surface is seated against a sealing socket in the flared end of the first pipe. Complementary bayonet coupling members on the locking ring and on the locking flange, respectively, are provided whereby the joint may be assembled by pressing the locking ring and the locking flange together against the resistance of the wave spring and rotating them relative to each other to engage the bayonet coupling.
