The rings are formed such that force of the circlip releases limit of a pivot angle range, where the angle range is limited between 90 and 120 degree. The bolt and the circlip are made of metal, and the rings are made of plastic and comprise a breaking section. A locking socket comprises a threaded sleeve with an external thread. |
