Abstract: The invention relates to a hose connector with an inner sleeve (2) and an outer sleeve (3) between which an annular space (5) is formed at least in a first end region (4), in which annular space one end (7) of a fluid line (8) is received. Furthermore, the invention relates to a method for the fluid-tight connection of one end of a fluid line to a hose connector. The hose connector is intended to be permanently and securely connected to the fluid line with little effort. Therefore, by means of crimping the inner sleeve (2) and the outer sleeve (3) in the end region (4), a force-fitting and form-fitting connection between the end (7) of the fluid line (8) and the hose connector (1) is formed.
