An improved joint for using on a baby stroller, being structurally provided with a twofold engagement effect, is provided. Whereby, when the baby stroller is stretched or collapsed, the joint can be in engagement and latching state without providing of additional engaging members, and reducing of cost and convenience of using can be achieved. The joint is comprised mainly of a first connecting member provided on an upper bracing rod and a second connecting member provided on a lower bracing rod. Wherein, the first connecting member is provided at the rear side thereof with a receiving chamber for receiving a pulling component. The pulling component has an engaging piece being able to extend into an upper pivotal connecting portion on the bottom of the first connecting member by means of a spring. The second connecting member is provided in a lower pivotal connecting portion on the top thereof with a first engaging groove and a second engaging groove. When the baby stroller is stretched or collapsed to be in position, the engaging piece can be automatically engaged into a corresponding engaging groove to form a latching state.
