A latch or connector assembly that is adapted to attach a track to a rail along a platform of a merchandising shelf assembly. The connector assembly includes an adapter having a first end and an opposite second end such that the first end is adapted to be attached to the track and the second end is configured to be selectively attached to the rail. The adapter includes a first arm and a second arm, the first arm is spaced from a second arm such that the first arm can be resiliently biased relative to the second arm. An attachment member extends from the first arm and is configured to selectively connect to the rail. A press surface is configured to be pressed by a user to bias the first arm relative to the second arm to selectively connect the attachment member to the rail.
