A gripping device for gripping or grasping an object within a set of jaws utilizing a shape memory alloy material that is both simple of construction and suitable for use in space as well as on Earth. The shape memory alloy contracts when heated and operates to move the jaw bears in a given direction. When no heat is applied to the shape memory alloy, a returning mechanism moves the jaw bars in the opposite direction. The shape memory alloy material may be in the form of a strap or wire which is easily heated and provides for a fast closing and opening action of the jaws of the gripping device.
