A joint for a playpen includes a main base, two wing base at two sides of the main base and fixed with two frames of a playpen, a press block, and two plate hooks. The two plate hooks, fixed on the press block, have two barbs to engage a position pin of each wing base in a spread position of the playpen, preventing the joint from being collapsed even if the press block is accidentally pressed when the playpen is in the spread position, keeping the playpen in the spread position in a quite safe condition. |
