Tube locking washer?

[Chamberlin]

I would like to know the name or where I can find more information on a type of washer or ring that goes over a plastic type tube which then can be inserted into a bore and when you pull back on it, it locks in place.
Alternativly any type of fastner that will lock one tube into another.

Thanks
darren.
