PURPOSE:To prevent a drop of force for tightening a connector main body to a tightening ring due to the lapse of time by interposing a spring washer and a flat washer between the connector main body and a tapered ring. CONSTITUTION:When a connector main body 2 and a tightening ring 3 are tightened to each other at specific torque, an axial direction load is always applied to them by a spring washer 6 and a flat washer 7 interposed between the engaging surface 2b of the connector main body 2 and the end surface of a tapered ring 4. Consequently, it is possible to prevent alleviation of a stress due to a change with the lapse of time and maintain the initial tightening force. The spring washer 6 is preferably housed inside an annular groove 2c formed on the engaging portion 2b of the connector main body 2.
