Abstract
A coupling is disclosed for connecting conduits that carry combustion air to an internal combustion engine. Two conduits are provide, a first one having an associated locking collar with slots and flexible locking fingers, and a second one having several outwardly facing pins and catches located on an outer surface. The pins are received in the slots and the two conduits are rotated with respect to each other. The catches and locking fingers engage to prevent the two conduits from being pulled apart. Both conduits and locking collar are preferably made of plastic, with the second one and its associated locking collar being simltaneously and integrally molded. A resilient seal may be located between the two components to reduce or eliminate air leakage.
