A hose connection unit comprises a hose (30) and a pipe connection which is pushed into it. The pipe has a ring shaped projection (21,22,23) with an outer dia. which is larger than the inner hose dia., and a hollow cylindrical end between the projection and the free end of the connection pipe. The hollow cylindrical end (18) is arranged so it is in tight contact with the inner hose wall, and the end is at least 3 mm long.
