Abstract: A fastening device of the type used to fasten panels together, such as the lid on a trunk, which is essentially recessed in both the locked and unlocked positions thus avoiding any protrusion of the assembly parts. The operating mechanism, which may be of the cam type, is fixed within the recess of the base plate. The slide member which is moved by the operating mechanism is bent upwardly toward the rim of the recess and terminates in a hinge member also within the recess. A catch member is hinged to the slide member and spring loaded so that the spring will rotate the catch member into the recess in the unlocked position.
