A magnetic recording tape cartridge comprising a bottom section and a top section assembled to the bottom section to provide a cartridge case. There are provided combinations of elongated holes in plan view and projections engageable in the elongated holes on both sections respectively to secure the bottom and top sections. Two of the securing combinations are specifically aligned and designed so as to eliminate horizontal displacement during assembly so that both sections can be easily joined in an accurate manner.
