This nail ( 2 ) comprises a body ( 4 ) that can be inserted into the medullary canal ( 108 ) of the humerus ( 100 ), this body ( 4 ) comprising a proximal part with housing orifices into which interlocking devices ( 22 ) such as screws will be inserted to interlock initially split humeral fragments ( 106 ₁- 106 ₃), and a locking device ( 6 ) capable of locking the said interlocking means ( 22 ), this locking device ( 6 ) being free to move relative to the body ( 4 ). The locking device ( 6 ) comprises several openings (6₁), each of which comprises a free passage part ( 6 ₁₁) extending in front of a corresponding orifice ( 4 ₄) in the free passage position, and a locking part ( 6 ₁₂), the walls of which can stop in contact with a corresponding interlocking device ( 22 ), in the locking position.
