A fastening system or mechanism for fastening a cover member of a first, resilient material to a base member of a second, relatively rigid material to form a tape cartridge housing comprises a single rigid fastener connected between the base and cover members and at least one expansion or slip fastener rigidly connected to one of the members and loosely connected to the other member in a manner permitting a predetermined degree of relative sliding movement between the members in any direction in the plane parallel to the base and cover members, while restricting perpendicular movement between the members. In the preferred embodiment, the expansion fastener comprises a headed post or screw extending through an enlarged opening in one of the members with some free play and fastened in an opposing bore in the other member. |
