Find a used one if you can, gluing plastic usually doesn't work well. But, if you are going to glue it anyway (like I always do) get a two part epoxy that can be used on plastics.
Make sure it is clean and dry the use plain old silicone and forget it the hole/crack will be completly sealed and repaired as soon as the silicone drys. Just make sure you have it squeezed / pressed into the opening.
it's called seal all you may have to put a few coats on it comes in a yellow tube. if you cant find this then use silicone.good luck
