Device for connecting a shoe to a sports implement

A device for removably coupling a shoe to a frame of sports implement, said device comprising:

• at least one first front abutment and retention element, which is fixed to said frame, and which is configured for engaging a front seat formed at a tip region of said shoe for containing longitudinal, lateral and perpendicular movements of said tip region with respect to said frame;
• a second self-fastening rear abutment and retention element comprising a lever which is articulated to said frame and which is configured for engaging a rear seat formed at a heel region of said shoe for containing longitudinal, lateral and perpendicular movements of said heel region with respect to said frame, said second self-fastening rear abutment and retention element further comprising a spring element which is connected between said frame and said lever for biasing said lever forwardly towards said first front abutment and retention element, and said first and second abutment and retention elements being mutually configured such that, upon engagement of said first front abutment and retention element with said front sear of said tip region of said shoe and upon pressing of said heel region of said shoe at said second self-fastening rear abutment and retention element, said lever pivots initially rearwardly away from said first front abutment and retention element until said lever pivots subsequently back towards said first front abutment and retention element and engages with said rear seat of said heel region of said shoe for providing an automatic self-fastening of said rear abutment and retention element.
