Abstract
A strap fastener of a swimming flipper uses the resilience of a spring to press a wedge block of a wedge block set and a bevel of a main body to tightly depress the fastening strap of the swimming flipper. For fastening, the said flipper fastening strap goes vertically into the fastener to improve the fastening method of bending the traditional fastening strap reversely at 180°, to eliminate the situation of bending and cracking generated after a certain period of application and to increase the useful life of the present invention. Moreover, the fastening strap of the swimming flipper of the present invention goes vertically into the fastener, closely attaches to the main body of the swimming flipper and turns along with the direction of flowing water during swimming or diving to thereby reduce the water resistance and enhance the diving efficiency.
