Claim:
A pneumatic conveyor comprising: a tubular channel ( 1 ) having edges, defining in its lower part a guidance and propulsion track ( 2 ) to transport products, said guidance and propulsion track ( 2 ) having nozzles ( 11 ) at regular intervals for the ejection of pressurized air in the direction of transport of the products, and on either side of its lower part with means ( 3 ) of maintaining the upper part of the products within said guidance and propulsion track ( 2 ), said tubular channel ( 1 ) being supplied with pressurized air by means of corresponding pressurized air conduits ( 4 ), with means of control linked to a central control unit by means of electrical wiring ( 5 ), wherein, on the tubular channel ( 1 ), at regular intervals, a means of guidance and support ( 6 ) of the pressurized air conduits ( 4 ), the electrical wiring ( 5 ), and a plurality of covers ( 7 ) having sides, are click-locked on said means of guidance and support ( 6 ) sequentially in an end to end fashion, which cover the corresponding edges of the tubular channel ( 1 ), while providing a clearance ( 8 ) between said corresponding edges and the sides of the plurality of covers ( 7 ), wherein the means of guidance and support ( 6 ) of the pressurized air conduits ( 4 ) and the electrical wiring ( 5 ) include, transversally, at least one subdivision ( 6 ′) and its lateral edges include vertical flanges having a cross section, having a hook ( 6 ″) at each end thereof, each end of each hook ( 6 ″) having exterior edge open to the exterior and designed to cooperate with at least one corresponding locking rib ( 7 ′) of the corresponding lateral edge of each of the plurality of covers ( 7 ).
