Can't you take the wife back? There's an ironic pun in there somewhere, stuck with the wife etc, but that's for you to finish!!!
But it all depends. Araldite is just a brand name for glue made of (most often) epoxy resin. And if the job in hand is cosmetic I'd happily use it on many plastics. Especially the reinforced Epoxies and polyesters will work fine and PVC and PU PolyUrethanes too. If the job is structural go get the "right" stuff, and always clean and degrease first and then roughen the surface with some abrasive.
However, if the plastic to be bonded is a non-polar such as PE (PolyEthylene) or PP PolyPropylene, even the "right" Araldite will struggle to adhere to it. These materials need surface treatment to bond properly (additional to cleaning and roughening that is).
Simplest treatment is to oxidise the surface with a flame/torch, but careful, they melt and distort quite easily.
