Abstract (en)

[origin: FR2752905A1] The invention concerns a fraud-proof pipe connection in particular for water metres. It consists of a detachable standard pipe fitting, of which the thread ring gauge (6) and the socket (9) to be mounted on the end of the pipe to be connected each comprise respectively an internal and an external groove capable of coinciding when the two pieces are in a predetermined position, so as to enable an elastic slotted ring (12) located in the groove of the ring gauge to be partially inserted in that of the socket thus securely blocking the two pieces in that position, thereby preventing any screwing or unscrewing of the ring gauge. The invention concerns the industrial and commercial field of piping accessory manufacture and distribution and is essentially for use by water supply companies, although it can be used for other purposes.
