Separation device assemblies

A separation device assembly comprising:

• a first plate having a first end member, a second end member, and a separation wall extending between the first end member and the second end member, the first end member and the second end member each defining a respective contact surface and a respective engagement surface;
• a second plate having a first end member, a second end member, and a separation wall extending between the first end member and the second end member, the first end member and the second end member each defining a respective contact surface and a respective engagement surface;
• and
• a fracture groove located on each of the separation walls proximate a respective first end member;
• wherein the first end member, the second end member, and the separation wall of the first plate define a first plate expansion device channel and the first end member, the second end member, and the separation wall of the second plate define a second plate expansion device channel,
• wherein, when the respective contact surfaces of the first and second end members of the first plate contact the respective contact surfaces of the first and second end members of the second plate, the expansion device channels of the first and second plates form an expansion device cavity,
• wherein, when the respective contact surfaces of the first and second end members of the first and second plates are joined, the first and second plates form a frangible joint;
• and
• wherein the respective engagement surfaces are configured to engagement with receiving channels of attachable mounting devices.
