These pieces are made integral with a U-shaped support 10, in relation to which they can be locked by shoes 60 and 70 which are held in position by a single securing screw 50. The pieces 20 and 30 can be connected to elements which are to be positioned, such as pins or connection rods which form part of an orthopaedic external fixing appliance consisting of pins inserted into bone fragments and of an external frame with connection rods.
