Here's a key section...I'm not saying this means anything, but as I have previously mentioned the IP continues behind the scenes .....
"Snap 215 may extend either from flange 214 (as shown) or directly from housing 201 in embodiments in which flange 214 is absent (see, e.g., FIG. 3A showing snap 331 extending outwards from housing 311). Snap 215 may be designed to engage retaining feature 217. Retaining feature 217 may take the form of, for example, an indentation, channel, or other receiving feature formed in inner surface 219 of housing 203 (as shown). In a preferred embodiment, snap 215 may form an integral part of housing 201 and be formed of the same material and as part of the same manufacturing process as housing 201. Retaining feature 217 may similarly form an integral part of housing 203 and be formed of the same material and as part of the same manufacturing process as housing 203. Snap 215 and feature 217 may be formed from any suitable material that allows snap 215 and/or feature 217 to be elastically deformed when housing 201 is inserted into housing 203. In particular, snap 215 and feature 217 may be formed of an elastic material, i.e. a material with high elasticity which allows snap 215 and/or feature 217 to bend or deform without yielding when a force is applied to them, and to regain their shapes once the force is removed. For example, snap 215 and feature 217 may be formed of an amorphous metal alloy having a high elasticity and an ability to bend without yielding (e.g., liquidmetal, vitreloy, metallic glasses). In embodiments in which both snap 215 and feature 217 are made of elastic materials, snap 215 and feature 217 may be deformed by substantially the same amount (measured as, e.g., the same distance from the snap's or the feature's rest position, or the same distance from their positions when the housings are coupled) when housing 201 is inserted into housing 203. In some embodiments, snap 215 and/or feature 217 may remain deformed while housings 201 and 203 are secured to each other. In other embodiments, snap 215 and/or feature 217 may only be deformed while housing 201 is being inserted into housing 203."
