ABSTRACT:
A hose coupling includes two coupling halves which take a coupling end position by relative rotation against each other about a coupling path of no more than 180°. The hose coupling further includes a locking mechanism that prevents an unintended opening of the coupling. The locking mechanism comprises a latching mechanism, in particular a latching pin mechanism. The latching mechanism is automatically activated in the coupling end position and prevents a relative rotation of the coupling halves against each other. The latching mechanism is preferably configured such that, already before reaching the coupling end position, the latching mechanism is activated so far that it counteracts a relative rotation of the coupling halves in an opening direction.
