A straight spring (230) is secured between spring retaining grooves (240) of the latch member (120) and wire support members (250) latch stops (270) are provided to restrict rotation of the latch member (120) about the hinge and prevents separation of the prongs (210, 220) upon excess rotation of the latch member (120) with respect to the hang-up cup housing (100).
