Abstract:
1. A hose coupling including; two coupling halves which take a coupling end position by relative rotation against each other about a coupling path of no more than 180°, and wherein the two coupling halves comprise cam pieces which are substantially of a common structure and have cams which can be brought into engagement in a bayonet lock manner with pitched shoulders of a respective other coupling half to limit the coupling path, and each coupling half comprises a spring-loaded latching pin, a latching hole corresponding to the coupling end position, and at least one additional latching hole; and a locking mechanism operating against an unintended opening of the hose coupling, the locking mechanism comprising a latching mechanism that is automatically activated in the coupling end position and prevents a relative rotation of the coupling halves against each other, and wherein the latching mechanism comprises a latching pin mechanism that is configured such that the latching pin can engage either in the latching hole in the coupling end position, or the additional latching hole in a position different from the coupling end position, thus blocking a decoupling movement of the coupling halves.
