Wheel adapter/lock not permanently durable?

Servus! Was the last time at the tyre dealer to have the winter tires mounted. The fitter told me that I should replace the rim lock (the wheel screw for which this adapter is needed) with a normal screw. He would have experienced many cases in which this lock was turned round and the screw could not be opened any more. I wanted to ask if you have heard similar things? I actually assumed that this special screw and the Adapters should already be able to deactivate it…
