A swimming fin comprising a blade (2) extending from a shoe (3) open at its rear side and with a rear heel strap (4) connected at the sides of the shoe by at least one buckle (5), said buckle comprising a base plate (6) integral with the shoe, a buckle arm (8) connected to the strap so as to allow adjustment of its tension and an intermediate lever (7) connected pivotally to the base plate and to the arm, reversible attachment means (17, 20) also being provided for connecting the intermediate lever to the base plate to achieve closure of the buckle. Between the intermediate lever (7) and the base plate (6) disengageable articulation means are provided (14, 18a), for achieving reciprocal engaging between them and a pivotal connection and, at the same time, allowing their separation in the direction opposite to that of tensioning of the strap. In this way, the intermediate lever can be separated from the base plate following release of the attachment means and disconnection of the disengageable articulation means.
