Absolutely inoperable!

We have this "Ballhupe" bolted to a PUKY bike our 5 year old daughter. Without aids such. As a fabric belt can this "Ballhupe" not even fix firmly, because if I would tighten the screws properly, breaks the cheap plastic holder. Will now be added the problem that a so considerable force is necessary in order to even get a sound out of this horn, which caused at the aforementioned fixation certainly no later than the 10th attempt to break the holder. If parents give their children these Ballhupe not as such, but only as a small "bicycle doll without function", it saves you some sad moments of gifted child. Nice to look at for each Lillebi fan, but no more than that !!!
