Heel strap (2) for swimming fins (1) with an open foot pocket (101), characterised in that it comprises a tubular element (3) made of elastomeric material with a hole (103) and end elements (4, 8) for coupling to the foot pocket (101) of the fin (1), each end element (4, 8) being provided with a seat (404, 408) in which at least one constriction (504, 508) is produced and through which, on one side, an end of the tubular element (3) is inserted, which is consequently elastically compressed at said constriction (504, 508) and expands after passing through the same, there being inserted on the other side of said seat (404, 408) and of said constriction (504, 508) an element (7) for locking the length of tubular element (3) that has passed through said constriction (504, 508) in the hole (103), so as to elastically expand it and to prevent, in combination with said constriction (504, 508), said tubular element (3) from being separated from said end coupling elements (4, 8) to which it is thereby permanently coupled. |
