A tape cassette is provided with interlocking wall sections to protect it against mechanical and/or thermal deformation. Advantageous interlocking connecting means are stepped teeth, peg-and-hole connections and connections in the form of prism-shaped projections and matching recesses. Such interlocking connecting systems can be used with particular advantage in film, audio, video and data cassettes and all kinds of storage containers which are required to exhibit great flexural strength.
