Claims

[Scope of utility model registration request]

A connecting fitting main body, a cap nut screwed onto the connecting fitting main body, and a cap nut that is pushed and moved into the connecting fitting main body by tightening the cap nut.
a retaining ring having an engaging portion formed at the protruding end to externally engage with one valley portion near the tube end of the metal flexible tube;
When the retaining ring is pushed into the connecting fixture body by the maximum amount, the inner circumferential portion of the connecting fixture body is directly opposed to the engaging part of the retaining ring and is connected to the engaging part. 1. A connecting fitting for a flexible metal tube, characterized in that an annular clamping pressure part is formed between the tube end portions of the flexible metal tube to clamp and hold the tube end portion of the flexible metal tube in a crushed state.
