A method for fastening a hose end in a hose clamping device, in particular a hose clamping device of a coupling element of a hose coupling, wherein - the hose end is drawn or pushed on the radial outside onto an inner sleeve, - a clamping sleeve is pushed on the radial outside over the hose end and pressed by means of an outer sleeve against the hose end and the inner sleeve, wherein - a hose casing of the hose end is clamped between the clamping sleeve and the inner sleeve, and the hose casing - lies between clamping sleeve and inner sleeve in a non-sealing region in the region of the end face of the hose end and is clamped in a non-sealing manner by clamping sleeve and inner sleeve and - lies, with a region of the hose end adjoining axially on the region of the end face of the hose end on the hose side, in a sealing region between clamping sleeve and inner sleeve and the hose casing of the hose end is clamped in a sealing manner here, characterized in that - the clamping sleeve and the inner sleeve are provided in the sealing region with oppositely formed protrusions (42, 42') and depressions (40, 40'), which - clamping the hose casing between them - interlock, wherein lateral flanks (43, 43'), which are each aligned radially or slightly inclined in relation to the axial direction, of the protrusions (42, 42') and depressions (40, 40') are pressed against one another and clamp the hose casing between them in a sealing manner, - while in the non-sealing region, which adjoins axially in the direction of the hose end face, without protrusions (42, 42') and depressions (40, 40'), no sealing effect results, but - holding elements, with which the clamping sleeve is provided in the non-sealing region, are pressed radially against the hose end with the aid of the outer sleeve, so that they penetrate into the hose casing of the hose end and hold it. - the hose end is drawn or pushed on the radial outside onto an inner sleeve, - a clamping sleeve is pushed on the radial outside over the hose end and pressed by means of an outer sleeve against the hose end and the inner sleeve, wherein - a hose casing of the hose end is clamped between the clamping sleeve and the inner sleeve, and the hose casing - lies between clamping sleeve and inner sleeve in a non-sealing region in the region of the end face of the hose end and is clamped in a non-sealing manner by clamping sleeve and inner sleeve and - lies, with a region of the hose end adjoining axially on the region of the end face of the hose end on the hose side, in a sealing region between clamping sleeve and inner sleeve and the hose casing of the hose end is clamped in a sealing manner here, - a hose casing of the hose end is clamped between the clamping sleeve and the inner sleeve, and the hose casing - lies between clamping sleeve and inner sleeve in a non-sealing region in the region of the end face of the hose end and is clamped in a non-sealing manner by clamping sleeve and inner sleeve and - lies, with a region of the hose end adjoining axially on the region of the end face of the hose end on the hose side, in a sealing region between clamping sleeve and inner sleeve and the hose casing of the hose end is clamped in a sealing manner here, - lies between clamping sleeve and inner sleeve in a non-sealing region in the region of the end face of the hose end and is clamped in a non-sealing manner by clamping sleeve and inner sleeve and - lies, with a region of the hose end adjoining axially on the region of the end face of the hose end on the hose side, in a sealing region between clamping sleeve and inner sleeve and the hose casing of the hose end is clamped in a sealing manner here, - the clamping sleeve and the inner sleeve are provided in the sealing region with oppositely formed protrusions (42, 42') and depressions (40, 40'), which - clamping the hose casing between them - interlock, wherein lateral flanks (43, 43'), which are each aligned radially or slightly inclined in relation to the axial direction, of the protrusions (42, 42') and depressions (40, 40') are pressed against one another and clamp the hose casing between them in a sealing manner, - while in the non-sealing region, which adjoins axially in the direction of the hose end face, without protrusions (42, 42') and depressions (40, 40'), no sealing effect results, but - holding elements, with which the clamping sleeve is provided in the non-sealing region, are pressed radially against the hose end with the aid of the outer sleeve, so that they penetrate into the hose casing of the hose end and hold it.
