How do I remove tyre repair kit bracket?

Has a bolt in the middle with 12 points. I need to get the bracket out to clean underneath, can anyone help with how I can do this?

Thanks

Spline is what that type of "grip" is called.

Search for ‘ multi spline tool ‘ or even ‘ triple square tool’ on google you will find a tool ,they come in various sizes like any other socket.

As was mentioned above, this socket is commonly called "triple square" but the correct name is "XZN".

You'll need an XZN bit of the correct size to remove it.
