ABSTRACT:
A tube connecting device includes a first tubular connector and a second tubular connector which extends into the first connector and which is formed with an annular peripheral groove that is registered with a pair of radial openings in the first connector. Each of a pair of press arms has one end mounted pivotally to the first connector adjacent to a respective one of the radial openings and formed with a cam face. Each of the press arms is pivotable to a locking position in which the cam face thereof extends into the peripheral groove via the respective radial opening so as to press against the second connector. Each of a pair of retaining units includes a positioning rod which is provided slidably in a positioning bore that is formed in an inner side of a respective press arm. A biasing unit biases the positioning rod so that an end portion of the latter engages a respective retaining seat which projects outwardly from the first connector when the respective press arm is in the locking position.
