A magnetic tape cassette comprises a housing having an open front side and two adjacent reel hubs containing an amount of tape, a span of said tape extending along the front side; at one or at both corner points near the open front side front covers are pivotable between an open position, and a closed position which covers at least partly over the front opening; the span of the magnetic tape which extends along the open front side can be moved between an active position outside the housing and an inactive position in which the tape is disposed between the major walls of the housing. Each front cover is formed with a thrust portion which during the pivotal movement from the open position to the closed position presses against the span of magnetic tape which extends along the front side and thereby moves it from the active position to the inactive position.
