1. Hose connector system (1) for an agricultural spreader machine (15) for spreading granulated or ground material such as fertiliser or seeds, whereby the material is transported through dimensionally stable hose lines (2), whereby one end of the hose line (2) is inserted into an opening (3) at an outlet (4) and the other end of the hose line (2) is inserted into an opening (6) at an inlet (7), whereby at least one end of the hose line (2) is fitted with an additional outer sleeve (9), which is placed detachably onto the end of the hose line and projects at least partially into an opening (3, 6) at the inlet (7) or outlet (4), whereby the opening (3, 6) and the outer sleeve (9) are designed to be lockable towards each against axial movability,
characterised in that the inside surface of the outer sleeve (9) has one or more elevations (10) that form the clear inside diameter of the outer sleeve (9) and the clear inside diameter of the outer sleeve (9) is less than the nominal diameter of the outer surface of the hose line (2) in the inserted state, whereby the outer sleeve (9), whose internal diameter is partially constricted by elevations, presses with its elevations into the partially elastic material of the hose line (2). |
