An improved safety locking mechanism according to the invention is particularly suitable for use in a five or more folding collapsible umbrella. The mechanism comprises a specially designed runner in conjunction with an actuator element. A plunger and a spring are disposed under the actuator element in a through hole formed on the runner. The plunger is urged by the spring and so will project out to abut against the upper rim of the bowed resilient element when the umbrella is opened. With such arrangements, an umbrella can be effectively kept at an open state. To close the umbrella users depress the bowed resilient element to make the plunger disengaged from the runner.
