Locking device intended as a fastening means for protheses, such as leg and arm protheses, of the kind where the prothesis is to be fastened to a cylindrical part such as a pin, an axle, a tube or the like. The locking device comprises a cage (18) with a ring of balls (19) arranged therein, said ring of balls by means of spring action is pressed into a conical seat (20) in the cage, at which the locking device is locked to the pin (12) or the like in axial direction while rotational movement is admitted. The locking device further comprises actuating means (24) for releasing the ring of balls (19) from the conical seat (20), at which the cage (18) is arranged in a housing (16) provided with a through opening for receiving said pin (12) or the like, said opening (16) has a larger diameter than the pin or the like in order to admit this to be inserted also in an oblique position. |
