The invention relates to a hose connection device, comprising: a hose line (20) having an elastic, dimensionally stable hose, by means of which hose a gas flow is transported； an insertion receptacle (22), an insertion opening (24) being arranged in a surrounding wall (23) of said insertion receptacle； and an insertion component (21) having a through-hole for transporting the gas flow. The insertion component (21) can be inserted into the insertion opening (24) by means of a proximal end piece (31). A hose end of the elastic, dimensionally stable hose is held at a distal end piece (25) of the insertion component. The proximal end piece (31) has at least one resilient tongue (32； 33) having a locking protrusion (34； 35). An edge (40) of the wall (23) surrounding the insertion opening (24) has a saddle shape on a side facing away from the insertion component (21). When the proximal end piece (31) is inserted into the insertion opening (24), the insertion component (21) can be rotated between a coupling position, in which the locking protrusion (34； 35) of the resilient tongue engages behind the edge (40) in the region of first edge sections in a locking position, and an uncoupling position, in which the resilient tongue (32； 33) is pressed inward in such a way that the locking protrusion (34； 35) is arranged in a non-locking position at least partially on an inner surface of the surrounding wall (23) facing the insertion opening (24), in the region adjacent to second edge sections, and is preloaded against the inner surface. The invention further relates to an agricultural distribution machine for dispensing granulated or granular material such as fertilizer or seed.
