A clip for use as a sinker for fishing, comprising two half-shells (1, 2) forming jaws having the shape of spherical sectors of the same diameter. The sector of at least one of the half-shells (1, 2) subtends an angle less than 180 DEG . The half-shells (1, 2) are assembled with each other about a pivotal axis (D) forming a common diameter of the half-shells (1, 2) by a resilient blade (3) anchored on the half-shells (1, 2) at a point (8) on that diameter. The resilient blade (3) is so shaped as to exert a continuous gripping action maintaining the two half-shells (1, 2) in a closed position. The elastic blade (3) imparts to the half-shells (1, 2) two over-center positions in each of which confronting edges of the half-shells rest against each other. These two over-center positions are spaced apart by an intermediate position in which the resilient blade (3) and the pivotal axis (D) lie in a common plane. Thus, the half-shells tend to snap into either one of two equilibrium positions in which they are yieldably maintained by the resilient blade (3).
