ABSTRACT:
A connecting device is adapted to releasably hold a portion of a first object, such as a pilot's oxygen mask, to a portion of a second object, such as a pilot's helmet. The connecting device broadly includes an anchor member mounted on the mask, a housing member mounted on the helmet and having a female passageway, a male member adapted to be inserted into the female passageway, and a cable member having one marginal end portion secured to the anchor member and another marginal end portion secured to the male member. The housing member has a toothed pawl section biased to move into the female passageway. The male member has a ratchet rack adapted to engage the pawl section to prevent unintended separation of the male member from the female passageway. The male member includes a release member movably mounted relative to the rack, and having an operative surface adapted to extend beyond the rack teeth. The release member may be selectively moved relative to the rack to disengage the mating teeth of the rack and pawl section to permit the male member to be withdrawn from the female passageway.
