Abstract: A latch device is provided for attaching interior linings, panels, or other surface components to an interior structure or part, such as the passenger compartment of an aircraft, without using any tool. The latch device has a latch base, a support member having a latch groove positioned rearwardly of a forwardly projecting tongue, a latch pawl above the latch groove movable under spring pressure between a pawl-detent position and a pawl-release position, and an actuator member having a striker pin retained between spaced-apart arms and an actuator end part at its opposite end. An edge portion of an interior lining is aligned with the striker pin and fed onto the tongue and into the latch groove against the spring pressure on the latch pawl, and can readily be removed by levering the actuator end part to unlatch the pawl from the striker pin.
