Abstract: The subject invention discloses a connector body positioning mechanism that pulls a pair of connector bodies together, against a high resistance force, to a fully seated position. A cam crank axially retained to one connector body turns in a plane normal to the direction of relative connector body motion, drawing a pair of helical grooves along an opposed pair of projections in the other connector body. A releasable latch retains the cam crank in a postion that properly registers the grooves and projections. Turning the handle back breaks the connection with the same highly leveraged force.
