A child-resistant closure includes a base, and a lid integrally molded and coupled to the base by a hinge. The lid has a latch arm resiliently extending from a periphery opposite the hinge and having oppositely extending tabs adjacent to a free end of the latch arm. The base has an external recess for receiving the latch arm and spaced ledges in the recess for engagement by the tabs to lock the lid in a closed position. The latch arm is engageable by a user to pivot the latch arm radially inwardly within the passage and release the tabs from the ledges so the lid can be pivoted toward an open position. The tabs and the ledges are recessed radially inwardly from the outer surface of the latch arm in the closed position of the lid with the tabs engaged beneath the ledges.
