A closing element of plastic for beverage containers (1) comprises a main body (2) with a circular-cylindrical shape defined by an upper surface (3) and a lower annular liner (4) made in a single piece to enclose an end portion of the container (1). The closing element further comprises a lateral portion having a pair of weakened and/or tear lines (9a, 9b) extending from the free edge (4a) of the annular liner (4) for a length equal to a third dimension ©. The two lines (9a, 9b) are separated, at their end sections, by a first dimension (A) and, at the free edge (4a), by a second dimension (B). The lateral portion (10) defined by the pair of lines (9a, 9b) is acted upon by a tab (11) associated with the annular liner (4) and designed to separate the closing element from the neck (6) so as to open the container. The first dimension (A) of the pair of lines (9a, 9b) is equal to the second dimension (B) calculated at the free edge (4a) from which the tab (11), forming an extension of the lateral portion (10), extends. The extension (L) of the tab (11) outside the limits of the free edge (4a) is greater than the second dimension (B).
