Connector - distributor mainly intended for the alternating control of pneumatic actuators. It includes a distributor mechanism of the type having three orifices and two positions, monostable returned by springs and controllable by a pressure signal, consisting of two pistons (2 and 3) joined by a rod (14) passing through two seats (6 and 7) and carrying, on their opposing faces, valves (66 and 77) controlling the alternating passage of the fluid through the said seats. The body (1) made from a moulded material, is closed in a leaktight and non-removable fashion by two plugs (4 and 5) in which there slide the pistons (2 and 3) which thus have no direct contact with it. The apparatus also acts as a connector and its outlet orifice (20b or 23) includes, for this purpose, a means for its leaktight and orientable fixing to a pneumatic component and its inlet orifices (18 and 19) include cartridges for instantaneous connection of a pressure pipeline of which the connection to one or other of the said orifices determines the "normally closed" or "normally open" operation of the apparatus. Application to pneumatic techniques. <IMAGE>
