A retractable handle includes two parallel sleeves, two inner tubes joined by a hand grip and moved in and out of the sleeves, and a control bar having two opposite beveled ends respectively inserted into the inner tubes and coupled to the hand grip by a respective slip joint, wherein when the control bar is depressed, the beveled ends are moved downwards to force two spring-supported retainer rods of the inner tubes out of respective locating holes on the sleeves, permitting the inner tubes to be pushed upwards by springs inside the sleeves, and therefore the inner tubes can be pulled out of the sleeves by the hand grip.
