Abstract: The invention relates to pliers (1), comprising two plier legs (2, 3) and a jaw opening (M) formed by jaws (7, 8), wherein retaining elements (9) that can be rotated relative to a jaw (7, 8) are arranged in the jaw opening (M) in order to grasp ends of a spring clamp (11) and the plier legs (2, 3) are connected to each other in an intersection region (4). According to the invention, in order to provide pliers for installing or removing spring clamps that are ergonomically designed as favorably as possible with regard to hand forces to be applied, the plier legs (2, 3) can be adjusted relative to each other in steps in the intersection region (4) in order to change the size of the jaw opening (M).
