A crowd control barrier including a barrier member with side legs and feet connected to the legs, each foot having a foot member extending transverse to the barrier member. The leg-foot connections include a bracket extending up from the connected foot member and spaced substantially parallel top and bottom pins on the legs. The bracket has a substantially vertical slot above a transverse slot with the top pin slidably received in the vertical slot and the bottom pin movable transversely in the transverse slot. Teeth project upwardly from the bottom of the transverse slot with the teeth upper ends spaced less than the pin spacing from the bottom of the vertical slot. Lifting a leg slides the top pin up in the vertical slot and moves the bottom pin above the teeth whereby the leg and foot may be pivoted about the top pin whereby the bottom pin moves transversely in the second slot.
