ABSTRACT:
An inflation manifold and a clip that snap fittingly engages it so that the manifold and clip assembly resists rotation and retraction relative to an inflatable article when they are molded into a thickened part of the article. The clip is generally annular and in a first embodiment is preferably divided into four independently formed parts that transiently diverge when the base part of the manifold is driven into the clip and which regain their initial position of repose after the base has traveled therepast, capturing said base and preventing its retraction. Both the base and clip are provided with apertures or bores or cutaways that fill with flowable elastomeric material when the inflatable article is molded so that the manifold and clip become an integral part of the inflatable article when the elastomeric material hardens. In a second embodiment, the clip is integrally formed and is molded into capturing relation to the base. In both embodiments, a cutaway is formed in the base so that hard or soft plastic fills the cutaway and further locks the manifold against rotation, the former being employed when increased rotation resistance is desired.
