A magnetic pulse generator for measuring wheel revolutions of bicycles includes a magnet and an attachment device for attaching the magnet to a component (or spoke) of a wheel. Damage to the component to which attachment is to take place is to be prevented, and the installation expenditure during attachment is to be reduced. Furthermore, the magnetic pulse generator known from practical application is to be improved in that it is applicable to components of various geometric shapes, in particular to round components of various diameters and to flat components spokes of various widths. This object is met with an attachment device that includes a housing that encompasses the component, and that is formed as a longitudinally slit tubular piece. Ends of the housing forming the longitudinal slit can be connected to each other in a positive-locking and/or non-positive manner, and a spacing (A) therebetween is variable.

The invention claimed is: 1. A magnetic pulse generator for measuring wheel revolutions of bicycles, comprising; a magnet and an attachment device for attaching the magnet to a movable component of a wheel, wherein the attachment device comprises a housing that encompasses the component, wherein the housing is formed as a longitudinally slit tubular piece, wherein first and second ends that form a longitudinal slit that are connectable and disconnectable relative to each other in a positive-locking and/or non-positive manner, wherein the housing comprises two housing parts that are movably connected to each other, and wherein a spacing (A) between the two housing parts is variable. 2. Them magnetic pulse generator according to claim 1, wherein connection means are provided for connecting the first and second ends that form the longitudinal slit, the connection means providing a snap-in connection. 3. The magnetic pulse generator according to claim 2, wherein the connection means comprise several snap-in teeth, and a force effect required for attachment is set depending on a geometry of the component. 4. The magnetic pulse generator according to any one of claims 2 or 3, wherein connection of the first and second ends of the housing are adapted to be disconnected by use of a tool. 5. The magnetic pulse generator according to claim 1, wherein a lateral cross section of the housing is non-symmetrical in shape, and one of the two housing parts is larger than the other of the two housing parts, wherein the larger housing part comprises magnet. 6. The magnetic pulse generator according to claim 1, wherein the housing comprises a retainer for fitting around the component wherein the component is a spoke. 7. The magnetic pulse generator according to claim 6, wherein in order to prevent rotation and slippage, the retainer comprises rubber, which in an operating position contacts the component. 8. The magnetic pulse generator according to claim 7, wherein the rubber is a rubber insert arranged so as to be fixed in a recess in each of the two housing parts. 9. The magnetic pulse generator according to claim 6, wherein a longitudinal axis (E) of the housing or of the retainer of the housing and a longitudinal axis (F) of the component in an operating position are substantially coaxial relative to each other. 10. The magnetic pulse generator according to claim 1, wherein the two housing parts form a tubular piece that is divided into two in a longitudinal direction. 11. The magnetic pulse generator according to claim 1, wherein a height of the housing is approximately 7 mm. 12. The magnetic pulse generator according to claim 1, wherein a tensile force generated by the magnet is approximately 3.8 kg, and a space (G) between the magnet and a sensor that receives pulses in a non-contacting manner is up to approximately 10 mm. 13. A magnetic pulse generator for measuring wheel revolutions of bicycles, comprising; a magnet and an attachment device for attaching the magnet to a spoke of a wheel, wherein the attachment device comprises a housing that encompasses the spoke, and wherein the housing includes first and second housing parts which form a longitudinally slit tubular piece, wherein ends of the first and second housing parts form a longitudinal slit and are connectable and disconnectable relative to each other in a positive-locking and/or non-positive manner, and a spacing (A) between the first and second housing parts is variable, and further comprising a recess formed in the first housing part facing a recess formed in the second housing part, a rubber insert being provided in each of the two facing recesses in order to prevent rotation and slippage of the attachment device relative to the spoke, the two rubber inserts being visible when the attachment device is viewed in a plan view and bottom view. 14. The magnetic pulse generator according to claim 13, wherein a larger one of the first and second housing parts comprises the magnet. 15. The magnetic pulse generator according to claim 14, wherein the first and second housing parts are pivotably connected to each other by way of at least one hinge. 16. The magnetic pulse generator according to claim 15, wherein the two housing parts and the hinge are formed in one piece. 17. The magnetic pulse generator according to claim 16, wherein the two housing parts and the hinge are made from plastic. 18. The magnetic pulse generator according to claim 15, wherein a longitudinal dimension of the hinge is shorter than that of the two housing parts.
