Patent attributes
An attachment part for an electric toothbrush is disclosed. The attachment has a brush head, a tubular connecting piece being connected to the brush head for connecting the same to the head of a toothbrush handle, and a drive shaft for driving the working head. The connecting piece has at least one interior latching element that is arranged such that it is suitable to move into the interior of the neck of the handle and to create a disengageable connection of the attachment part to the neck of the handle, the interior latching element being radially inwardly offset, with regard to the diameter thereof, relative to an internal cylindrical surface of the connecting piece, such that a gap remains between the exterior of the interior latching element and the internal cylindrical surface, the gap being suitably made such that a wall of the neck of the handle can be moved into it.
