You don't need to pass, you can get this in your fragment, but anw, you can pass mClipboardManager from your activity into you fragment by 2 way

1. Set value from your activity.

First, get fragment instance using getFragmentManager().findFragmentByTag("YourFragmentTag")

in your fragment, create a method

public void setClipboardManager(ClipboardManager clipboardManager) {
  // here you get an instance of clipboardManager, do anything you want
}

and call this method in your activity:

fragment.setClipboardManager(mClipboardManager)

2. Get the value of mClipboardManager from you fragment

First, create a method in your activity

public ClipboardManager getClipboardManager() {
   return mClipboardManager;
}

then, in 

@Override public void onAttach(Context context) {
        super.onAttach(context);
        if (getActivity() instanceof YourActivity) {
            ((YourAcitivity) getActivity()).getClipboardManager()
            // here you get an instance of clipboardManger, do anything you want
        }
    }
