An engaging structure for a pair of locking pliers, comprising: a fixed handle with a groove, an adjustable jaw, a side handle with a groove, an elastic member, a restricting member with a groove and a linking member with a supporting portion, the restricting member including a first pivoting portion to be inserted and pivotally connected in the groove of the side handle, the linking member being arranged in the groove of the restricting member and pivotally connected with a second pivoting portion of the restricting member, and the second pivoting portion lies in the groove of the side handle; characterized in that: an engaging structure of the restricting member extends from a top edge of one side of the groove of the restricting member; when the pair of locking pliers is open, the engaging structure is positioned against a top edge of one side of the groove of the side handle, so as to prevent the side handle and the fixed handle from being further pried apart, and when the pair of locking pliers are closed, the supporting portion of the linking member is pressed against the groove of the side handle; the engaging structure of the restricting member is Z-shaped.
