Abstract
The present latch apparatus includes a swinging piece having first and second independent latches or sliders sliding in first and second slots. The first and second sliders slide independently of each other. The first and second sliders engage an undersurface of an extension of a first object such as a gate. If either the first or second slider is engaged on the undersurface, the swinging piece is locked and is not swingable such that the first object such as the gate cannot itself swing away from a second object such as a barrier section. Only when each of the first and second sliders has been slid beyond the undersurface can the swinging piece swing to permit the first object such as the gate to be released and thus swingable itself relative to the second object such as the barrier section.
