A device for temporary holding of an object on a support (6), comprises a female body (4) intended to be fixed to the support and a male element (2) linked to the object. In this female body there are provided retaining means adapted, on the basis of their relative axial position with respect to a frustoconical guidance ramp (19) which is integral with the body and opens out towards the object, to be retracted radially onto an annular radially projecting portion of the male element or to be moved away therefrom under the action of manoeuvering means comprising a manoeuvering jack rod (7) which is coaxial with the male element. Ejection means (8) integral with this rod, bearing on the male element in the holding phase, are adapted to come to push the object towards the outside of the body. The retaining means comprise a socket comprising a transverse annular flange (14) from which extend a plurality of radially flexible blades (15) which are elastically loaded radially outwards, extending towards the male element, and whose free ends carry retaining jaws (16). <IMAGE>
