A transparent window member for a tape cassette, which together with a reel pressure spring, forms a subassembly of the cassette. The reel pressure spring has a U-shaped central portion, the bight of the U being parallel to the plane of the spring arms, and the reel pressure spring having a longitudinal edge with two transverse slits spaced the same as the legs of the U of the central portion of the pressure spring. The central portion may thus be transversely inserted in the longitudinal edge of the window member and it thus forms a locating element for the pressure spring.
