Abstract
So as to temporarily connect two elements, such as an artificial satellite lengthening piece and the body of this satellite, a device is used including a holding mechanism (22) of any structure and a freeing member (20) made of a form memory material. The holding mechanism (22) normally applies a holding mechanical tension between the elements. When it is desired to free these elements, the freeing member (20) is heated by, for example, a heating resistor (28) or by using solar energy, until it reaches the transformation temperature of the form memory material. The disposition of the freeing member (20) is such that its change of form suppresses the mechanical holding tension and creates a positive allowance between the elements.
