Abstract
A magnetic tape cassette, particularly a video tape cassette which is provided with a hinged front panel prestressed by a tension spring, the coil of which is positioned on an axle on the inside of the side wall of the front panel. The free end of the long spring leg grips beneath the front of an upper housing half of the cassette, which constrains the long spring leg. A lower housing half has a hinged locking plate on the inside, in the area of the front panel. The locking plate has a obliquely extending projection projecting over the plate, which projection being eccentric to the center of rotation of the plate has a surface off set from the axis of rotation of said hinged locking plate, and on the surface of oblique projection the long spring leg stressed between the upper housing half and the projection of the plate to produce a moment of force on the plate tending to swing the plate on the axis of rotation.
