The present invention relates to a coupling head for coupling a towing vehicle to a trailer. According to the invention, in the coupling head a filter element is used. The filter element is bypassed by a continuously open by-pass. Preferably, the path through the by-pass has at least one redirection in the region of an undercut. As a result of the redirection, contaminants in the compressed air are not or not fully transferred through the by-pass. The by-pass might also ensure a supply of compressed air to the trailer, for example, when the filter element is at least partly blocked due to the contaminants. According to the invention, a valve element used to open the by-pass in the case of increasing blockage of the filter element is not required.
