1. A winding bobbin for accommodating a yarn bobbin, comprising a hollow-cylindrical tube body (1), wherein the tube body (1) is designed to be inserted onto a bobbin mandrel (8), characterized in that a fastening element (3) is provided on at least one end face (2.1) of the tube body (1), wherein the fastening element (3) is designed to be elastically deformable for radially tensioning the tube body (1) on the circumference of the bobbin mandrel (8).

2. The winding bobbin according to claim 1, characterized in that the fixing element (3) is deformable on the tube body (1) by an axial movement of a plurality of tube bodies (1) on a bobbin mandrel (8).

3. The winding bobbin according to claim 1 or 2, characterized in that the fixing element (3) is formed by a rubber ring (4.1,4.2) fixed in a groove (5.1,5.2) in the end face (2.1,2.2) of the tube body (1).

4. Winding bobbin according to claim 3, characterised in that the tube body (1) has rubber rings (4.1,4.5) on both end faces (2.1,2.2), respectively, which rubber rings (4.1,4.5) are designed to protrude from the end faces (2.1,2.2) of the tube body (1) in the relaxed state.

5. The winding bobbin according to claim 1 or 2, characterized in that the fixing element (3) is formed by a plurality of resilient clamping tongues (9) on the end faces (2.1,2.2) of the tube body (1), the resilient clamping tongues (9) being arranged to be evenly distributed over the circumference of the tube body (1).

6. The winding bobbin according to claim 5, characterised in that the axially projecting clamping tongues (9) of the tubular body (1) are designed ramp-like for being push-fitted on the clamping cone (10).

7. The winding bobbin according to claim 6, characterized in that the tube body (1) has clamping cones (10) on the opposite end faces (2.1,2.2), the clamping cones (10) being capable of being pushed onto the clamping tongues (9) of an adjacent tube body (1').

8. The winding bobbin according to claim 1 or 2, characterized in that the fixing element (3) is formed by a plurality of clamping tongues (14) designed to be spaced apart from each other on the end faces (2.1,2.2) of the tube body (1), there being a plurality of clamping protrusions (15) between the clamping tongues (14), wherein the clamping protrusions (15) of adjacent tube bodies (1) can be push-fitted onto the clamping tongues (14).

9. The winding bobbin according to claim 8, characterized in that a plurality of clamping tongues (14) and a plurality of clamping protrusions (15) are each designed to be offset from each other on both end faces (2.1,2.2) of the tubular body (1).

10. The winding bobbin according to any of the preceding claims, characterized in that the tube body (1) has a radially encircling doffing slot (19) on the circumferential surface, the doffing slot (19) being assigned to one of the end faces (2.1, 2.2).

11. The winding bobbin according to any of the preceding claims, characterized in that the tubular body (1) has a plurality of axial grooves (18) designed to be distributed on the inner diameter, the plurality of axial grooves (18) passing completely through the tubular body (1).
