The support for offset socket keys, each key comprising a first arm and a second arm which extend in a plane Q, comprises a body which is provided with a series of openings which extend in a plane P and a retention unit for retaining the series of keys relative to the body (4), the keys being offset vertically relative to each other. The retention unit is laterally offset relative to the plane P and is arranged sloping relative to the body in order to retain the vertically offset keys in the storage and transport position, in parallel planes Q which deviate angularly from the plane P.
