The invention concerns a movement restricting apparatus designed to prevent an animal from reaching with its mouth or some of its limbs, a zone of its body to be protected. The apparatus comprises features for fixing the apparatus to the animal and for restricting movement being attached or linked to each other. A dorsal slide on the feature for restricting movement is designed to be placed perpendicular to the animal's saggital symmetry, against the top of a part of its spine, and is in the form of a profiled section with open or closed cross-section.
