A cassette assembly which holds at least two electrical plugs which typically are connected to digital signal carrying cables. In one example, six of these plugs are positioned within a cassette, and are arranged in two rows of three plugs each for ease in connecting the plugs simultaneously to similarly arranged switch port jacks. A lever pivotally connected to the housing, when rotated, causes the release latch of the plugs held within the cassette to move from a locked to an unlocked position to simultaneously remove all of the plugs from the jacks to which they are connected. A housing clip is provided to be positioned within the housing of the cassette assembly such that a projection of the clip is positionable within a path of removal of a plug. A locking clip is also provided for blocking movement of the lever wherein the locking clip is easily installed with the cassette with providing a generally U-shaped constriction with opposing arms, a compression resistant member positioned between the arms and a tab positioned on each arm adapted to engage an aperture defined in a cassette plug housing. In addition, bridge clips are provided to gang together two or more cassette assemblies.
