Abstract

The present invention relates to a closing device for closing pressure fluid conveying channels in a housing by a closing member press fitted into a channel, the outside periphery of the closing member including at least one indentation into which, by press fitting the closing member into the channel, basic material of the housing is deformed to provide a form lock. The housing is made of a malleable aluminum alloy, and the closing member is made of steel.
