Abstract: A hose connecting device has a connector, an inner locking ring, an outer connector and a tubal body. The connector has an insertion section and an engaging section, the engaging section has a size greater than the insertion section, and the engaging section further has a stopping ring at a top end. The inner locking ring is jacketed onto the engaging section of the connector and abutting the stopping ring of the connector. The inner locking ring has an outer threaded section and an abutting portion disposed at a bottom end of the inner locking ring. The outer connector has one of a female connector and a male connector, and a channel, the channel has a positioning step at a middle portion, an inner threaded section disposed below the positioning step of the channel. The tubal body is jacketed onto the insertion section of the connector.
