I don’t think there is such a character. At least I have never seen him.
Please note: if you use Windows, you can simply type charmap.exe , select a Unicode compatible font, and view all available characters. Probably similar tools are available for other operating systems.
What else could you use as a symbol for application plugins?
You can use different things depending on the context. The plus + symbol may be one that symbolizes probably the best idea of the plugin (IMHO is even better than a piece of the puzzle, because the plugin is what adds the function to the software, and not the part that needs to be combined with other parts to form whole application).
Why not use an icon? Keep in mind that using an unusual Unicode character can cause some problems with Unicode-compatible software, browsers, and environments.
