My understanding is you can cut off and join and use "any" power cord plug lying around your home, maybe a appliance you were going to trash or a spare extension cord you have lying around, any cord plug you have will meet your countries specs for rating/safety, when joining just make sure you separate the live earth and negative with insulation tape if wire are exposed, you probably wont need to if you use a plastic connector , I use the screw in type connectors to join the 3 wires, seriously you dont need to buy a plug, you probably has one lying around, use it., just conect the 3 wires. . or just buy a extension cord and cut of one end.
