An easily separable but conventional-appearing hinge wherein the hinge flaps can be connected or disconnected to/from one another without relative lengthwise displacement of the flaps by employing short axial movement of the hinge pin. The flaps thus may be hingedly securely connected together, or disconnected and separated within limited space. The flaps have tubular knuckles with adjacent space or gaps so knuckles of one flap can be interdigitated with knuckles of the other flap and held together by the hinge pin. Knuckles of one flap are slotted longitudinally forming open sided or split tubes; those of the other flap are fully tubular, i.e., unslotted. The removable hinge pin has adjacent cylindrical and flat portions, the latter positionable in gaps longitudinally aligned with the full tube knuckles of one of the flaps. The slotted knuckles of the other flap can be fitted transversely over the pin's flat portions thereby axially aligning the knuckles of both flaps with the pin fully encased and axially slidable therein. So positioned, the flaps can be disengaged by sliding the slotted knuckles in reverse transverse direction until free of the pin's flat segments. The flaps lock together for normal hinge action, or unlock for separation, by short axial movement of the pin between a locked position in which the pin's cylindrical portions are within the slotted knuckles and an unlocked position in which the pin's flat portions are within the slotted knuckles. One flap has a spring well with coil spring therein axially of the hinge pin to normally bias the pin to the flap-locking position. Pin actuator means can be provided to move the hinge pin between locked and unlocked positions and to rotate the pin to direct edges of the flat segments towards the slots of the open-sided knuckles.
