The present invention relates to a device for securing a shaft to collar connection (16) of two shafts (12, 14), in particular for securing a PTO shaft stub (14) of a PTO shaft of a tractor. The device comprises a locking element (40) preventing a disconnection of an established shaft to collar connection (16) between the two shafts (12, 14) in axial direction. One of the two shafts (12) comprises a collar (15) with a positive engagement element (38) for a locking engagement with the other shaft (14). The other shaft (14) comprises a positive engagement (22) for a locking engagement with the shaft (12) comprising the collar (15). The locking element (40) is basically ring-shaped and arranged at the first of the two shafts (12). In order to enable an easier handling of the axial locking of the shaft to collar connection (16), it is suggested, that the locking element comprises a toothing (44), which is basically complementarily formed to the toothing (22) of the second of the two shafts (14). The locking element (40) is rotatably arranged on the first shaft (12) and can be rotated from a locked position to an unlocked position. In the locked position the toothing (22, 44) is arranged such that they overlap. In the unlocked position the toothing (22, 44) is arranged such that they do not overlap. The locking element (40) is arranged such that in the locked position of the locking element (40) an established shaft to collar connection (16) is secured by the engagement of the toothings (22, 44) of the two shafts (12, 14). Furthermore the present invention relates to a shaft (12) of the locking device.
