Failure of push-to-connect couplings which, for example, connect re- inforced hoses to ports in valve bodies is prevented by an anti-rotation collar. The ports have a projecting external hex nut fixed to the valve body. A rigid tube is received within the push-to-connect coupling which in accordance with a first embodiment, has fixed thereon a collar with a pair of arms having flat surfaces which engage opposed flats on the hex nut. In accordance with the second and third embodiments of the inven- tion, the anti-rotation collar has a projection, such as a pin, which is received in a hole fixed in the valve body. The collar has a hexagonal re- cess therein which reccives a hexagonal projection from the rigid tube which prevents rotation of the collar with respect to the tube. In this way, the tube is fixed with respect to the valve body and does not rotate so as to cause failure of a collet within the push-to-connect coupling which radially engages a first portion of the rigid tube to axially retain the rigid tube in the coupling. A second portion of the rigid tube has an end of the reinforced hose fixed thereto by either a crimping collar or a screw thread.
