The invention claimed is: 1. A rail switch frog (1) comprising: a movable frog point (5) slidingly guided within a cast or welded base frame (2) extending at least over generally the length of the frog point (5), said frog point being movable into abutment on wing rails (6, 7) mounted on the base frame (2) and laterally supported in its abutment positions by supporting elements (10) fixed to said base frame (2), and an end-position securing device (12) for resiliently pressing the frog point (5) in its abutment position against the wing rail (6, 7) and the supporting elements (10), wherein the end-position securing device is arranged within a space delimited by said base frame (2), and is attached to said base frame (2), or the supporting elements (10), as well as to the frog point (5). 2. A frog according to claim 1, wherein the end-position securing device (12) is fixed to a carrying part connecting two neighboring supporting elements (10). 3. A frog according to claim 2, wherein a rail-side hinge point of the end-position securing device (12) is located in a region of a center-of-gravity plane of the frog point (5). 4. A frog according to claim 3, wherein the end-position securing device (12) is a spring rocker. 5. A frog according to claim 2, wherein the end-position securing device (12) on a rail side is connected to a holding part (11) embracing a rail foot of a long point (3) and a rail foot of a short point (4). 6. A frog according to claim 5, wherein the end-position securing device (12) is a spring rocker. 7. A frog according to claim 5, wherein a rail-side hinge point of the end-position securing device (12) is located in a region of a center-of-gravity plane of the frog point (5). 8. A frog according to claim 7, wherein the end-position securing device (12) is a spring rocker. 9. A frog according to claim 2, wherein the end-position securing device (12) is a spring rocker. 10. A frog according to claim 1, wherein the end-position securing device (12) on a rail side is connected to a holding part (11) embracing a rail foot of a long point (3) and a rail foot of a short point (4). 11. A frog according to claim 10, wherein a rail-side hinge point of the end-position securing device (12) is located in a region of a center-of-gravity plane of the frog point (5). 12. A frog according to claim 11, wherein the end-position securing device (12) is a spring rocker. 13. A frog according to claim 10, wherein the end-position securing device (12) is a spring rocker. 14. A frog according to claim 1, wherein a rail-side hinge point of the end-position securing device (12) is located in a region of a center-of-gravity plane of the frog point (5). 15. A frog according to claim 14, wherein the end-position securing device (12) is a spring rocker. 16. A frog according to claim 1, wherein the end-position securing device (12) is a spring rocker. 17. A frog according to claim 16, wherein the end-position securing device (12) is a spring rocker. 18. A rail switch frog (1) comprising: a movable frog point (5) slidingly guided within a base frame (2), said frog point being movable into abutment on wing rails (6, 7) and laterally supported in its abutment positions by supporting elements (10) fixed to the base frame ( 2), and an end-position securing device (12) for resiliently pressing the frog point (5) in its abutment position against the wing rail (6, 7) and the supporting elements (10), wherein the end-position securing device is arranged within a space delimited by the base frame (2), and is connected with the base frame (2), or the supporting elements (10), as well as with the frog point (5), wherein the end-position securing device (12) on a rail side is connected to a holding part (11) embracing a rail foot of a long point (3) and a rail foot of a short point (4 ), and wherein the holding part (11) embracing the rail foot of the long point (3) and the rail foot of the short point ( 4) is connected with the frog point (5) by a pin (18) passing through a rail stem of the long point and the short point ( 3, 4), respectively, in a region of center-of-gravity planes of the long point and the short point (3, 4). 19. A frog according to claim 18, wherein a rail-side hinge point of the end-position securing device (12) is located in a region of a center-of-gravity plane of the frog point (5). 20. A frog according to claim 19, wherein the end-position securing device (12) is a spring rocker. 21. A frog according to claim 18, wherein the end-position securing device (12) is a spring rocker. 22. A rail switch frog (1) comprising: a movable frog point (5) slidingly guided within a base frame (2), said frog point being movable into abutment on wing rails (6, 7) and laterally supported in its abutment positions by supporting elements (10) fixed to the base frame ( 2), and an end-position securing device (12) for resiliently pressing the frog point (5) in its abutment position against the wing rail (6, 7) and the supporting elements (10), wherein the end-position securing device is arranged within a space delimited by the base frame (2), and is connected with the base frame (2), or the supporting elements (10), as well as with the frog point (5), wherein the end-position securing device (12) is fixed to a carrying part connecting two neighboring supporting elements ( 10), wherein the end-position securing device (12) on a rail side is connected to a holding part (11) embracing a rail foot of a long point (3) and a rail foot of a short point (4 ), and wherein the holding part (11) embracing the rail foot of the long point (3) and the rail foot of the short point ( 4) is connected with the frog point (5) by a pin (18) passing through a rail stem of the long point and the short point ( 3, 4), respectively, in a region of center-of-gravity planes of the long point and the short point (3, 4). 23.
