This is an SO239 to PL259 adapter with a connection for an earth wire.
The ground wire offers a low resistance path that will allow atmospheric static and electrical charges to be totally or partially bled off to the earth ground.
Redirecting these interfering charges will reduce and eliminate much of the hissing and popping noise heard in the receiver. The bleed may also save damage to the receiver circuits.
It does not have a fuse as with other more expensive protectors.
