1. A filtering device for the filtration of combustion air in internal combustion engines, comprising a soft yielding flexible filter element (2) of woven or non-woven synthetic polymers or cellulose, arranged in a filter housing,wherein the filter element (2) is hose-shaped,wherein a wall of the filter element (2) radially separates an unfiltered side and a filtered side,in that the hose-shaped filter element (2) is secured within a tubular sleeve support part (3), andin that the support part (3) is insertable between and detachably connected to an unfiltered fluid pipe (10) and a filtered fluid pipe (11) that are to be combined to a continuous flow pipe,wherein the support part (3) comprises a support sleeve (5) wall that radially surrounds axial end faces (12 and 14) of the unfiltered fluid and filtered fluid pipes (10 and 11),wherein the filter element (2) is located in an interior of the flow pipe,wherein the support part (3) includes a radially inwardly displaced fastening projection (4) secured to an inner wall of said tubular sleeve support part and extending radially inwardly from said inner wall into an open interior of said support part, said fastening projection includingaxially spaced opposing axial end faces (6,13) on opposing axial sides (6,13) of said fastening projection (4),wherein an end face (7) of said filter element (2) is seal-tightly axially clamped between a first one of said axially spaced opposing axial end faces (6,13) of said fastening projection and a facing axial end face (12,14) of one of said fluid pipes (10,11),wherein a second one of said axially spaced opposing axial end faces (6,13) of said fastening projection rests immediately against a facing axial end face (12,14) of a different one of said fluid pipes (10,11),wherein the end face section (7) of the hose-shaped filter element (2) rests immediately against at least one of the end faces (12 and 14) of the fluid pipe pipes (10 and 11),wherein the end face section (7) of the hose-shaped filter element (2) is clamped between and against the end face (12 or 14) of fluid pipe (10 or 11) and the support part (3),wherein said wall of said support part (3) includes locking recesses (8) extending through said wall from an interior to an exterior of said support sleeve, said locking recesses (8) detachably engaging locking noses (15) in said fluid pipes, connecting said fluid pipes together through said support part (3) by a releasable snap-in locking connection. 2. Filtering device according to claim 1, wherein on the fastening projection (4) an end face section (7) of the hose-shaped filter element (2) is secured. 3. Filtering device according to claim 1, wherein the support part (3) comprises a support sleeve (5) that radially surrounds axial end faces (12 and 14) of the unfiltered fluid and filtered fluid pipes (10 and 11). 4. Filtering device according to claim 1, wherein the filter wall of the hose-shaped filter element (2) is connected by means of an additional fastening site (17) to a component. 5. Filtering device according to claim 4, wherein the additional fastening site (17) is located on the support part (3) so that in the filter element (2) two parallel extending pockets (18, 19) extending in the flow direction are provided. 6. Filtering device according to claim 1, wherein a sealing ring (16) contacts and seals between an axially extending inner wall of the support part (3) and an axially extending exterior wall of at least one of the fluid pipes (10, 11). 7. The filter device according to claim 2, wherein the filter wall of the hose-shaped filter element (2) is connected by means of an additional fastening site (17) to a component. 8. The filtering device according to claim 7, wherein the additional fastening site (17) is located on the support part (3) so that in the filter element (2) two parallel extending pockets (18, 19) extending in direction of flow are provided. 9. The filtering device according to claim 7, wherein a sealing ring contacts and seals between an axially extending inner wall of the support part (3) and an axially extending exterior wall of at least one of the fluid pipes (10, 11). 10. The filtering device according to claim 1, wherein said filtering device including said support part and said hose shaped filter element is a modular one piece component with the filter element connected fixedly to the support part, wherein said filtering device including said support part and said hose shaped filter element is provided and replaced in one piece as a unit. 11. The filtering device according to claim 10, wherein a sealing ring contacts and seals between an axially extending inner wall of the support part and an axially extending exterior wall of at least one of the fluid pipes. 12. The filtering device according to claim 1, wherein said filtering device including said support part and said hose shaped filter element is a modular one piece component with the filter element connected fixedly to the support part, wherein said filtering device including said support part and said hose shaped filter element is provided and replaced in one piece as a unit. 13. The filtering device according to claim 12, wherein a sealing ring contacts and seals between an axially extending inner wall of the support part and an axially extending exterior wall of at least one of the fluid pipes.
