Summary:A keyless coupling for a tool shaft and a handpiece of a surgical instrument having a first coupling section, which is provided on a proximal section of the tool shaft, a second coupling section, which is provided on a distal section of a shaft holder of the handpiece, and a locking/unlocking element. The locking/unlocking element is arranged on the tool shaft and forms a latching section, and the shaft holder has an undercut for receiving the latching section in a locking position of the two coupling sections such that the latching section and the undercut are in latching engagement with one another and secure the two coupling sections against a relative axial movement with respect to one another at least in the pulling direction.
