PROBLEM TO BE SOLVED: To provide a connector with good operability, a few number of parts, of simple structure and compact size. SOLUTION: As shown in figure (a), an assembly nut 17 is inserted into a tip part 12 of an end bell 10 at a given angle so that four key grooves 18 and four key grooves 13 match with each other. Next, after a desired angle of a barrel 2 against an end bell and its nut is selected, four keys 3 of the barrel are made to pass through the key holes 18 to be inserted into each key hole 13, which is a state as shown in figure (c). Then, the nut is rotated, and the part without the key grooves 18 of the nut and each fitted part 19A pinch each key of the barrel and a locking part 14A of the end bell, as shown in figure (d). Thus, the barrel is prevented from slipping out of the nut. Here, a locked part 19B of the nut is locked to the a locking part 14B of the end bell.
