A connector comprises a base, a gate, and a locking mechanism. The base forms an opening. The gate is slidably operatively connected to the base and spans the opening. The locking member has an engaging position and a releasing position. The engaging position secures the gate to the base, and the releasing position allows the gate to be moved relative to the base.

A connector apparatus includes a first connector and a second connector. A housing defines a first channel and a second channel and a locking mechanism configured to secure one of the first and second connectors within the first channel or the second channel. The locking mechanism includes a disk with a rotational stop, and a latch arm pivotable between at least a latched position and an unlatched position. When the first connector is secured within the first channel by the disk and the second connector is inserted into the second channel, the second connector actuates the latch arm towards the unlatched position such that the disk is enabled to pivot and secure the second connector to the housing while simultaneously releasing the first connector from the housing.
