摘要：An electric toothbrush may be provided by combining an attachment part for an electric toothbrush such as an attachable brush head and a handpiece. The attachment part comprises a tubular connecting piece connectable to a neck of a handpiece by axial movement along a longitudinal axis thereof. The connecting piece may have at least one peripheral mating surface engagable with inner and/or outer peripheral surfaces of the neck of the handpiece, wherein a radially movable latching element is configured to lock the attachment part relative to the handpiece. A handpiece of the toothbrush having a neck provided with inner and outer peripheral surfaces to be coupled with the inner and outer mating surfaces of the attachment part. The coupling includes a latching element and a latching contour to lockingly engage each other.

主权项：1. An attachment part (3) for an electric toothbrush (1), comprising a tubular connecting piece (7) structured and configured to be connected to a neck (4) of a handpiece (2) of the toothbrush (1) by axial movement of the connecting piece (7) relative to the handpiece (2) along a longitudinal axis (19) thereof, said connecting piece (7) having at least one peripheral mating surface (9, 10) adapted to engage with an inner or outer peripheral surface (11, 12) of the neck (4) of the handpiece (2), wherein at least one latching element (30) is provided for locking the connecting piece (7) onto the neck (4), said latching element (30) being radially movable to lock and/or unlock with and/or from a latching contour (32) of the neck (4) by radial movement, characterized in that the latching element (30) is provided with a circumferentially sloped unlocking surface (31) for transforming a rotational movement of the connecting piece (7) about the longitudinal axis (19) of the tubular connecting piece (7) into a radial movement of the latching element (30).
