Abstract: The present invention is directed to a report cover combination that includes a slide lock. The slide lock includes a wall defining a channel. Two edges define a slit extending through the wall of the slide lock along its length, and the longitudinal ends of the slide lock are sloped toward the slit to facilitate the insertion of a folded edge of a report cover into the slit of the slide lock. Preferably two parallel lips protrude inward from the edges of the slide lock at the slit. The report cover includes front and back covers having an outer surface. The front and back covers are connected by a hinge. At least one protrusion extends from at least one of the covers adjacent the hinge. The hinge of the report cover is insertable into the channel of the slide lock through the slit. The protrusion is configured and dimensioned to catch against the opposing edges of the slide lock such that the report cover resists extraction from the slide lock.
