Abstract: An apparatus for connecting and disconnecting two objects comprises: a housing formed as a hollow type, and having one closed end to which a first object is connected and another opened end; a coupling portion mounted in the housing so as to be movable in an axial direction of the housing, and to which a second object is connected; a clamping portion coupled to the housing for clamping the coupling portion; a cylinder disposed in the housing for pressurizing the clamping portion so that a clamped state of the coupling portion by the clamping portion can be maintained; and a gas generator integrally coupled to an outer surface of the housing so as to be in communication with inside of the housing for generating gas of a high pressure thereby releasing a clamped state of the coupling portion and separating the coupling portion from the housing. Two objects are easily connected or disconnected to/from each other by the simple construction.

Abstract: An object separating apparatus uses gas and has a hollow housing with a closed end connected to a first object, and an opened end. An axially movable cylinder is installed at an inner space of the housing and a piston assembly is coupled to the cylinder and connected to a second object at an outer end. A fixing portion between the housing and the cylinder and the piston assembly fixes the cylinder and the piston assembly into the housing. A gas generator communicates with the inner space, wherein when the gas generator is operated, the gas generator pressurizes the cylinder to release the cylinder from the piston assembly and to separate the cylinder and the piston assembly from the housing.
