This invention relates to a spring two states of stable equilibrium. This spring is to be used for accumulation of elastic strain energy and for setting the mutual position of movable co-acting parts. The spring consists of at least one pair of elastic strips and two shaped elements determined by the angles, the elastic strips of each pair being connected to one another, preferably at their ends, with arms of the shaped elements in such a way that between the neighboring sides of the strips there is a slot of length and a variable width. Strips are situated in relation to one another in such a way that they are inclined at an angle as determined by the inclination angle of shaped elements. The invention is applicable for clamping various parts, for instance, for closing kinematic chains, for accumulation of elastic strain energy in bumpers, as well as for ensuring the state of equilibrium of component parts of various mechanisms.
