Patent abstract
A joint for tubings with which, in tightening the nut member (20), the friction torque applied to the first end face (32) of the control ring (30) by the bore peripheral face (25) of the internally threaded bore (21) of the nut member (20) is greater than the friction torque applied to the second end face (34) of the control ring (30) by the stopper portion (17) of the joint main body (10, and thus the nut member (20) is reliably turned together with the control ring (30) at the final stage of tightening the nut member (200, which allows the proper initial tightening position of the nut member (20) to be determined.
