(b) To each other;
(c) To a D-ring to which another snap hook or other connector is attached;
(d) To a horizontal lifeline; or
(e) To any object which is incompatibly shaped or dimensioned in relation to the snap hook such that unintentional disengagement could occur by the connected object being able to depress the snap hook keeper and release itself.
