105 each comprising a pin 106 and a bushing 107 the devices being arranged all around the nozzle these connection devices 105 maintain prestress f between a radial shoulder 113 of the divergent portion 103 b pressing against a corresponding radial shoulder 114 of the throat 103 a a sealing ring 115 between these shoulders 113 and 114 provides sealing for the connection between the throat 103 a and the divergent portion 103 b each pin 106 is housed at one end in a radial orifice 108 in a ring 109 of the throat 103 a and at the other end inside the bushing 107 which is itself housed in a corresponding radial orifice 110 of a ring 111 of the divergent portion 103 b this radial orifice 110 presents a shoulder 112 against which the bushing 107 comes into abutment the pin 106 and the bushing 107 may be seen more clearly in fig2 b and 3 thus the pin 106 presents two surfaces 106 a 106 b that are axisymmetric and more specifically cylindrical and that are eccentric relative to each other its first surface 106 a which presents a diameter d 1 is to be housed in the radial orifice of a first nozzle segment.
