PROBLEM TO BE SOLVED: To prevent a coaxial cable from being readily removed from a contact plug seat. SOLUTION: A locking connector 2 is fitted over a contact plug seat 20b provided in a series unit 1, and an F-shaped contact plug 3 provided at the end of a coaxial cable is attached to the contact plug seat 20b. In this case, a pair of parallel grooves 2b are formed in the locking connector 2 and fan- shaped engaging parts 5d formed on an exclusive tool 5 are inserted into the parallel grooves 2b. Thereby the fan-shaped engaging parts 5d engage the hexagonal part 3a of the F-shaped contact plug 3 contained in the locking connector 2. Thus, the F-shaped contact plug 3 can be threadably attached to the contact plug seat 20b by rotation of the exclusive tool 5. After attachment, the locking connector 2 covers the F-shaped contact plug 3 and thus precludes removal of the F-shaped contact plug 3. |
