Claim:
An instantly-released joint for water conduits, comprising: a first connector in hollow form, one end thereof is coupled to a water conduit, and the other end thereof is extruded to form a connecting rod having two locking elements on the top, as well as a peripheral groove adjacent to the front-end edge where an O-ring is provided; a second connector in hollow form, one end thereof is coupled to a water conduit, and the other end thereof is provided with locking holes on the surface; the inner wall of the second connector is provided with flanges in order to form a hole of smaller diameter; two corresponding grooves are provided on the front-end of the second connector such that the grooves can extend from the top of the second connector to the locking holes, in order to allow the locking elements on the first connector slide along the grooves to the locking holes for engagement purposes; and a pillar plug, having a close end and a free end which can operate as a valve; a larger outer ring is provided on the free end, while a leakage-proof flange is provided on the close end; by way of the above-mentioned elements, the first connector can be coupled to a water conduit at one end, inserted to the second connector with the connecting rod at the other end, and coupled to the second connector by turning the connectors at a certain angle to inter-lock each other; a pillar plug and a spring are further provided inside of the second connector such that the spring may be against the pillar plug via its flexibility; an O-ring is mounted on the peripheral groove of the first connector while another O-ring is mounted on the peripheral groove at the end of a pillar plug which passes through the second connector, rendering the whole assembly being instantly released.
