This disclosure is directed to a hinge fitting adapted to be secured to a leaf or frame and including a casing having a slot defined by a pair of spaced walls opening through interior and exterior surfaces of the casing, a locking member nonrotatably connected to a shaft which is in turn rotatably journaled to the casing and having an end portion with means for coupling a drive tool thereto for rotating the shaft to rotate the locking member to dispose a portion thereof beyond the casing and into gripping engagement with an associated leaf or frame. An axis of the shaft is disposed in eccentric relationship to the locking member and more closely adjacent one of the pair of spaced walls whereby the one wall serves as an abutment means to limit the outward disposition of the locking member beyond the casing.
