1. A closing cap (1; 1′; 1″; 1′″) for a container (2), comprising a lateral wall (3) extending around an axis (Z) and a transversal wall (4) positioned at one end of the lateral wall (3), a separation line (5) being provided on the lateral wall (3) to define a retaining ring (301), which comprises a retaining portion (303) which extends as far as a free edge (304) of the retaining ring (301) and is configured to internally engage with a locking ring (202) of a neck (201) of the container (2) in such a way as to remain anchored to the neck (201), and a closing element (302) removably engageable with the neck (201), so as to open or close the container (2) by rotating the closing element (302) around the axis (Z); the separation line (5) being circumferentially interrupted to define in the lateral wall (3) a joining zone (305) in which the retaining ring (301) and the closing element (302) are joined; the cap additionally comprising an incision line (7; 7′; 7″; 7′″), which is also provided on the lateral wall (3) to define, together with the separation line (5) at least a first connecting band (306) and a second connecting band (307) for connecting the joining zone (305) and the retaining portion (303) to each other; wherein the incision line (7; 7′; 7″; 7′″) comprises a pair of lateral stretches (702, 703; 702′, 703′; 702″, 703″; 702′″, 703′″) wherein a first lateral stretch of the pair of lateral stretches (702; 702′; 702″; 702′″) defines, with a first part of the separation line (5) which extends from a first end (501) of the separation line (5), the first connecting band (306) and a second lateral stretch of the pair of lateral stretches(703; 703′; 703″; 703′″) defines, with a second part of the separation line (5) which extends from a second end (502) of the separation line (5), the second connecting band (307); wherein the first and second lateral stretches (702, 703; 702′, 703′; 702″, 703″; 702′″, 703′″) have different angular extents to define the connecting bands (306; 307) having different lengths, the angular difference between the longer of the first and second lateral stretches and the other of the first and second lateral stretches being greater than, or equal to 5° and less than, or equal to 45°.
