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. A press arm has one end mounted pivotally to the first connector adjacent to each radial opening and formed with a cam face. Each press arm is formed with a positioning seat in which a positioning rod is provided slidably and is pivotable to a locking position so that the cam face thereof extends into the groove via the respective radial opening. A retaining seat is disposed below each radial opening and is formed with a vertical through-hole into which a first end portion of the positioning rod is biased to extend when the press arm is in the locking position. A locating projection is disposed immediately below each retaining seat. The positioning seat abuts against the respective locating projection when the respective press arm is in the locking position. A pair of guard plates are located on two sides of each retaining seat and each locating projection. Each pair of guard plates cover two sides of a corresponding press arm when the corresponding press arm is in the locking position.
