Abstract
A safety device for the foot-holder of a sailboard or the like in which the foot-holder has a strap in the form of a loop fixed at one end on the sailboard. The other end of the strap is secured to a latch which can be engaged in a locking body with a first elasticity in a first predetermined direction and then locked in the locking body with a second elasticity in a second direction perpendicular to the first predetermined direction. The latch and locking body are so arranged that under the action of a pulling stress exerted on the latch in the second direction, the latch is unlocked in a direction to enlarge the loop while remaining engaged in the locking body. But under the action of a shearing stress exerted on the latch in the first direction, the latch is released from the locking body and opens the hoop.
