Magnetic interlock

A magnetic interlock is a strong piece of technology.

Magnetic interlocks are used aboard Federation Starfleet starships as part of warp cores. Failure of magnetic interlocks could lead to a warp core breach. 

In 2378, a Satarran destroyed a Dokaalan facility that maintained a series of magnetic interlocks. The interlocks were used to keep together several asteroids that the Dokaalans had a colony on.
