Abstract
A safety stirrup detachably connected to the stirrup-leather in order to release the rider's foot in the event of a fall comprises a coupling device having two jaws for clamping the top portion of the stirrup head. A forward pivotal displacement of the stirrup with respect to the stirrup-leather causes rotation of a cam provided at the upper end of the stirrup head. The two jaws are opened-out by a top wedge of the cam through an angle of approximately 30.degree. to 45.degree. while a bottom wedge of the cam increases the separation of the jaws, thus releasing the stirrup.
