The invention relates to a toothbrush handle part having a handle part neck that can be inserted into the connecting piece of an attachment. Said attachment comprises a coupling device having at least one engaging piece for locking with the connecting piece of the attachment. The invention also relates to the above attachment comprising an attachment head and a tubular connecting piece connected to the attachment head, the connecting piece being placeable on the handle part neck of the toothbrush handle part and having a coupling device for locking the connecting piece on the handle part neck. The invention is characterized in that the axial movement in the longitudinal direction of the handle piece effects actuation of the coupling device and the transverse movement effects the locking. The toothbrush handle part is characterized in that its coupling device has a coupling piece which is axially movable in the longitudinal direction of the handle part, said coupling piece being received in such a manner that an axial movement of the coupling piece produces a transverse movement of the engaging piece of the coupling device at a right angle to the longitudinal direction of the handle part. The axial actuation movement can be produced when the attachment is placed onto or removed from the handle part neck.
