A device is provided for gripping the forearm of a user suffering from muscular problems in the elbow. The device defines a rigid but elastically deformable U-shaped body, and has a bottom. The device includes a first limb and a second limb, and two supporting elements which are mounted on the body such that each one is essentially located on a free end part of a limb of the body. One of the limbs of the body defines a first curved part which is adjacent to the bottom wherein the concave region of the curved part is oriented towards the inside of the body, and a second curved part which extends from the first part towards the free end of the limb. The concave region of the second part is oriented towards the outside of the body such that the limb of the U has a transversal flexion line.
