Abstract
The invention relates to a toothbrush (20), the brush head (22) of which can be removed from a brush handle (24). A threaded pin (26) can be moved to a limited extent out of the brush handle (24), counter to the action of a prestressing spring (32), when the brush head (22) is screwed onto the pin, until a stop catch (36) of the brush head (22) engages in a recess (38) of the brush handle (24) and locks the brush head in the rotational direction, while the prestressing spring (32) holds the brush head (22) under prestress against the brush handle (24). A firm connection can thus be established simply and rapidly between the brush handle and the brush head, irrespective of the shape of these parts.
