The invention relates to an arrangement for the detachable connection of a wiper blade on a swivelable wiper arm of a wiper arrangement for windows of motor vehicles, with a bushing that can be connected to the wiper blade or arranged on it for accommodating a plug-in axis of the wiper arm and with a device to lock the plug-in axis in the bushing at least in an operating position of the wiper blade, in which the directions of the longitudinal extension of the wiper blade and the wiper arm are aligned approximately parallel to one another. It is provided that the device for locking includes a catch hook (20) arranged on the wiper blade (12), which in the operating position partially grips around the wiper arm (10) near the plug-in axis (16) and forms an angular limit stop for the wiper blade (12).

The invention claimed is: 1. An apparatus for the detachable connection of a wiper blade (12) on a swivelable wiper arm (10) of a wiper for windows of motor vehicles, the apparatus comprising a bushing (18) one of connectable to the wiper blade and arranged on the wiper blade for accommodating a plug-in axis (16) of the wiper arm to define a pivot axis of the wiper arm and the wiper blade, and the apparatus comprising a device to lock the plug-in axis in the bushing at least in an operating position of the wiper blade, in which the directions of the longitudinal extension of the wiper blade and the wiper arm are aligned approximately parallel to one another, wherein the plug-in axis (16) extends transverse to the longitudinal extension of the wiper arm, wherein the device for locking includes a catch hook (20) arranged on the wiper blade (12), which in the operating position partially grips around the wiper arm (10) near the plug-in axis (16) and forms an angular limit stop for the wiper blade (12), the catch hook (20) being longitudinally spaced from the bushing on the wiper blade, the catch hook (20) having a first wall extending parallel to the pivot axis, the first wall being engageable with a portion of the wiper arm to provide the angular limit stop, the catch hook (20) having a second wall extending transverse to the pivot axis and to the first wall, wherein, in the operating position, the second wall is engageable with a portion of the wiper arm to limit axial movement of the wiper arm away from the wiper blade, the catch hook (20) having a third wall extending transverse to the pivot axis and to the first wall, the second wall and the third wall being on opposite ends of the first wall, wherein the wiper blade includes a connector (14), the connector (14) supporting the bushing (18) and the catch hook (20). 2. An apparatus according to claim 1, wherein in the operating position of the wiper blade (12), the catch hook (20) blocks an axial movement of the plug-in axis (16) in the bushing (18) to a large extent. 3. An apparatus according to claim 2, wherein the plug-in axis (16) can only be displaced in the bushing (18) in the axial direction in a pre-defined angular range that differs from the operating position. 4. An apparatus according to claim 3, wherein the wiper blade (12) can be separated from the wiper arm (10) in an angular position outside the operating position. 5. An apparatus according to claim 2, wherein the wiper blade (12) can be separated from the wiper arm (10) in an angular position outside the operating position. 6. An apparatus according to claim 1, wherein the plug-in axis (16) can only be displaced in the bushing (18) in the axial direction in a pre-defined angular range that differs from the operating position. 7. An apparatus according to claim 6, wherein the wiper blade (12) can be separated from the wiper arm (10) in an angular position outside the operating position. 8. An apparatus according to claim 1, wherein the wiper blade (12) can be separated from the wiper arm (10) in an angular position outside the operating position. 9. An apparatus according to claim 1, wherein the wiper arm has a first face and an opposite second face, wherein the plug-in axis projects from the first face, and wherein, in the operating position, the second wall of the catch hook (20) is engageable with a portion of the second face of the wiper arm to limit axial movement of the wiper arm away from the wiper. 10. An apparatus according to claim 1, wherein the wiper arm has a side wall extending between the first face and the second face, and wherein the first wall of the catch hook (20) is engageable with a portion of the side wall of the wiper arm to provide the angular limit stop. 11. An apparatus according to claim 1, wherein the wiper arm has a first face, an opposite second face and a side wall extending between the first face and the second face, wherein the plug-in axis projects from the first face, and wherein the first wall of the catch hook (20) is engageable with a portion of the side wall of the wiper arm to provide the angular limit stop. 12. An apparatus for the detachable connection of a wiper blade (12) on a swivelable wiper arm (10) of a wiper for windows of motor vehicles, the apparatus comprising a bushing (18) one of connectable to the wiper blade and arranged on the wiper blade for accommodating a plug-in axis (16) of the wiper arm to define a pivot axis of the wiper arm and the wiper blade, and the apparatus comprising a device to lock the plug-in axis in the bushing at least in an operating position of the wiper blade, in which the directions of the longitudinal extension of the wiper blade and the wiper arm are aligned approximately parallel to one another, wherein the plug-in axis (16) extends transverse to the longitudinal extension of the wiper arm, wherein the device for locking includes a catch hook (20) arranged on the wiper blade (12), which in the operating position partially grips around the wiper arm (10) near the plug-in axis (16) and forms an angular limit stop for the wiper blade (12), the catch hook (20) being longitudinally spaced from the bushing on the wiper blade, the catch hook (20) having a U-shape including a base portion extending parallel to the pivot axis and providing the angular limit stop, the catch hook (20) having a leg extending transverse to the pivot axis and to the base, wherein, in the operating position, the leg is engageable with a portion of the wiper arm to limit axial movement of the wiper arm away from the wiper blade, wherein the wiper blade includes a connector (14), the connector (14) supporting the bushing (18) and the catch hook (20).
