An electric toothbrush includes a handpiece with a drive shaft and attachment, which has a working head and a coupling member connecting the working head and the handpiece. The coupling member of the attachment contains a plug-on shaft to engage the drive shaft. An attachment coupling part is axially movable in a longitudinal direction to produce an unlocking or locking movement of the plug on shaft in the transverse direction. The connection can be released and re-established by axial push-on and pull-off movements. A transversely movable engagement part of a coupling contour of the plug-on shaft of the attachment and an actuating part provided on the coupling member are movable in the attachment longitudinal direction, such that relative movement of the actuating part and engagement part in the longitudinal direction produces an unlocking or locking movement of the engagement part in a direction transverse to the attachment longitudinal direction.
