Abstract: A protective device for at least two projecting parts of a limb, which parts extend outwardly in separate angular planes, the device including a flexible body at least partially surrounding the limb; a protection element made of a rigid or semi-rigid material locally distributed on the flexible body; an attachment system for the protection element on the flexible body; and a tightening element of the flexible body around the limb. The protection element includes at least one first part and one second part connected to one another by an articulation allowing a forced adjustment of the parts of the protection element with respect to the projecting parts to be protected when the tightening element is activated during tightening. The invention finds its application in protective devices used in skating, such as in-line skating, roller skating, or other similar sports.
