| 1. A microphone comprising:
a cylindrical microphone grip having a connector housing section on a rear side thereof, said connector housing section having
a connector therein and an internally threaded hole,
a microphone unit supported on a front side of the microphone grip,
a connection plug for a microphone cable, detachably connected to the connector in the connector housing section,
a push machine screw threadably engaging the threaded hole to be able to contact the connection plug for preventing the connection
plug from coming off from the connector, and
a protective sleeve formed of a rubber elastic element and having a machine screw holding hole therein, said protective sleeve
being detachably fitted around the connector housing section so that the machine screw holding hole is aligned radially with
the threaded hole and being securely fitted around the connector housing when the push machine screw engages the connector
housing section through the machine screw holding hole, said machine screw holding hole having a diameter smaller than that
of the push machine screw for holding the push machine screw therein by means of rubber elasticity so that the push machine
screw is held in the protective sleeve when the push machine screw is only retained in the machine screw holding hole.
