Abstract

A snap closure is provided for the detachable securement of a housing cover on a housing of a manually-guided implement, especially to secure an air filter cover that covers an air filter of an internal combustion engine for driving a tool of the implement. At least one snap hook is provided on one of the components that are to be secured together, namely the cover and the housing. The snap hook is provided on an end of an elastically deflectable leg that is disposed on the one component. The snap hook is tapered in the manner of a detent and when the cover is mounted on the housing the snap hook, accompanied by an elastic return force, is engagable in an undercut provided on the other component. The snap hook is deflectable in or parallel to a surface plane on the one component that carries the snap hook.
