Toy-like plastic strip for allowing turn-on

I'm currently working on an electronic design who need to be turned on just once and continue to run until the battery die.
I was searching for a way to do that and the most obvious was to use a plastic strip who act like a "remove before flight" lock.
A lot of toys and small consumer products use that but I didn't found any specific component which can allow that.
I know that on most of these devices, a plastic strip in inserted before the battery to prevent electrical connection between the circuit and the anode or cathode. But I would like to know if there is a component which could allow that without putting it on the battery. Since my design could make the initial launch very unpractical due to the position of the battery.
I will reply the first three comments:
- the product is shipped with the battery already inserted. Due to confidentiality reason, the final custommer don't have to access the device.
- Nice idea. Unfortunately, my geometrical limitations will probably not allow that. But I will study it.
- It's the only way for me to control that the system is launched only when really used by the final custommer. Long time stocking of the full product could impact the battery life during normal use.

You know how battery contacts are a bit springy? Well, forgetting the battery part, if you had two back-to-back with that bit of pull-out plastic between them, that would work. If you're getting lots made, you could probably get better-shaped springy metal.

You could use two PCB-mounted spring battery terminals mounted next to each other, so that the spring terminals are pressing together. They would probably have to be hand-soldered as they will try to push each other out of the board during soldering. Then add the plastic strip during manufacture, after testing but before assembly of the case.
For example, the Keystone 590.

Some smoke detectors with built in batteries have a one way catch, latch or clip that is used for a disable button. Once you slide it to the off position, plastic of the casing is used to prevent the user from sliding it back without damaging force or deconstruction. This is coupled with a switch.

How about just a simple slide switch?
Put a pulltab on the slide so it can only be pulled to the on side.
https://www.digikey.com/products/en/switches/slide-switches/213?FV=ffe000d5%2C1f140000&quantity=0&ColumnSort=1000011&page=1&stock=1&k=slide+switch&pageSize=25&pkeyword=slide+switch
I guess that it's similar to the PCB jumper onto pins idea, but perhaps a little more mechanically secure.
