Abstract: A lock and harness assembly includes first and second locks removably attached to each other. The locks are coextensively shaped, and are independently and simultaneously pivotal between folded and unfolded positions. Each lock has a linear medial edge conjoined to the other's medial edge when the locks are at a locked position. First and second harnesses traverse through the first and second locks. The harnesses are slidably positioned through the locks. Each lock includes a mechanism for statically holding the harnesses at a locked position such that the harnesses are prohibited from sliding through the locks after the locks have been coupled. Each lock includes a mechanism for releasably coupling the locks to each other such that the locks must be slidably adapted along a linear path defined orthogonal to the harnesses.
