The ethernet splitter adapters I find on Amazon all specify that you can use only one device at a time. I want to split one ethernet cable into two ethernet cables and be able to use the connexion on both devices at the same time.
----Eth cable 2-----> Device
Router ---Eth cable 1---> Adapter ----Eth cable 3-----> DeviceThe reason I want to do this, is because the router is far from the 2 devices and I much prefer passing only 1 cable (instead of 2) from one room to the other.
Is this possible?

Is there an adapter that exists to split an ethernet cable into 2 cables, allowing simultaneous use?
Yes, it is called a (Ethernet) switch.
Use one port to connect to the router in the other room.
Use two other ports for each device in this remote room.
Switch | | | | | +--------Eth cable 3-----> Device
Router ---Eth cable 1----+ | +----------Eth cable 2-----> DeviceNote that a switch will require electrical power, e.g. a wall wart.
Apparently your use of the word "split" has confused some responders, as that term is often associated with an Ethernet wiring hack.
With a switch the devices in the remote room are sharing the single cable to the router.
In networking terminology this is known as cascading or daisy-chaining.
See Cascading your Switch to Another Switch.
(If your router has more than one downstream port, then it has a integrated switch.)
You could pass a single cable and use an an ethernet cable sharing kit. See the connection diagram:
You still need to have two switch ports on one side, that will be sent to the other side, over a single cable, as two ports.
Or a switch. That's, I think, the best way to solve it.
