The present invention relates to a trench shoring apparatus, comprising: first and second side panels connected in a parallel spaced-apart configuration by a connecting bar pivotally connected to one end of one or more pairs of lateral arms, the other opposite end of the one or more pairs of lateral arms being hingedly connected to the side panels, such that translational movement of the connecting bar in a direction parallel to the side panels causes the spaced-apart panels to move between retracted and extended parallel spaced-apart configurations; and locking means for releasably restricting translational movement of the connecting bar.
