摘要： A pipe fitting 20 adapted for joining pipe 28, 30 comprises a swage ring 22, 24, 52 with a locking mechanism area 42, 63 which can lockingly engage with either a coupling body 26 and/or a pipe 28, 30, 56 which has a locking mechanism 44, 64 in order to prevent relative motion between the swage ring 22, 24 and the coupling body 26 and/or the swage ring 52 and the pipe 56. Such an arrangement prevents the swage ring 22, 24 from backing off of the fitting 20 should the fitting 20 be subject to flexing due to bending forces.
