An assembly for connecting a coaxial cable to an externally threaded connecting part. The connecting assembly has a tubular fitting with a central axis and axially spaced first and second ends. The tubular fitting includes a rotatable nut at the first end to threadably engage an externally threaded connecting part. The second end is adapted to receive a coaxial cable. The rotatable nut has a contoured surface portion configured to be operatively engaged by a complementary turning tool having a first configuration that is directed radially into turning engagement with the rotatable nut and useable to turn the rotatable nut around the central axis. The shield assembly extends around the rotatable nut and blocks radial access to the contoured outer surface by a turning tool having the first configuration. The shield assembly does not extend substantially beyond the rotatable nut towards the second end of the tubular fitting. The shield assembly is configured so that a second tool having a second configuration can be directed axially into turning engagement with the rotatable nut to facilitate turning of the rotatable nut around the central axis.
