A shield connector device comprising: first and second connectors, each of which includes a terminal (16, 26) connected to a terminal of a mating connector, a connector housing (11, 21) made of an insulating material, which accommodates the terminal and is provided with an operation opening portion (12, 22) for connecting the terminal to the terminal of the mating connector, and a service cover (13, 23) made of an insulating material, which is mounted to the connector housing to block the operation opening portion after a connection operation of the terminal; an electric wire, both ends of a conductor of which are respectively connected to the terminals of the first and second connectors; and a shield shell (50, 50A) made of a metal plate, which shields the first and second connectors and the electric wire, wherein the shield shell is divided into two sections including a first shield shell (51, 55, 56) fixed to the first connector and a second shield shell (52, 53) fixed to the second connector, wherein the service cover of the first connector is further provided with an interlocking portion which allows electrical connection to the terminal of the first connector when the service cover of the first connector is mounted to the connector housing of the first connector after the terminal of the first connector is connected to the terminal of the mating connector, and blocks electrical connection to the terminal of the first connector when the service cover of the first connector is detached from the connector housing of the first connector, characterized in that peripheral edges (51 a, 53a, 56a) of the first and second shield shells along a dividing line overlap each other in a state of enabling relative movement between the first shield shell and the second shield shell, wherein at least a part of the first shield shell is configured to be joined to the service cover of the first connector and thus to be attached to and detached from the connector housing of the first connector concurrently with attachment and detachment of the service cover, wherein at least a part of the second shield shell is configured to be joined to the service cover of the second connector and thus to be attached to and detached from the connector housing of the second connector concurrently with attachment and detachment of the service cover, and wherein a peripheral edge of the at least a part of the first shield shell joined to the service cover of the first connector overlaps an outer side of a peripheral edge of the at least a part of the second shield shell joined to the service cover of the second connector. first and second connectors, each of which includes a terminal (16, 26) connected to a terminal of a mating connector, a connector housing (11, 21) made of an insulating material, which accommodates the terminal and is provided with an operation opening portion (12, 22) for connecting the terminal to the terminal of the mating connector, and a service cover (13, 23) made of an insulating material, which is mounted to the connector housing to block the operation opening portion after a connection operation of the terminal;
