Abstract: A quick connector is adapted to be attached to a fluid-containing vessel, such as an aerosol can. The quick connector includes a body having a passage through which fluid can flow when the quick connector is attached to the vessel. The quick connector preferably includes an attachment mechanism in the form of a plurality of radially flexible legs angularly disposed around a longitudinal axis of the passage and extending proximally from the body. An inwardly disposed finger is disposed at the proximal end of each of the legs. The locking ring travels between a first position in which the legs are free to flex outwardly and a second position in which the legs flex inwardly such that the fingers engage the vessel rim when the quick connector is attached to the vessel. Some embodiments include a floating capitulator to accommodate vessels having fluid delivery stems of varying sizes.
