90mm timber butt joint for kids slide

[DSB]

Hello

I'm a complete wood work novice but have decided to build a play slide frame for my daughter.

I would like to join two 90mm timbers as shown in the photo below.

Does anyone know where I can purchase the green bracket shown in the photo or something similar?

Advice on how to join two 90mm timbers in this way also welcome. The joint will need to support the weight of a small child jumping up and down

Thanks

You may find something suitable - or even adaptable - if you Google some images of 'joist hangers'......one other way is to plant on some timber on the vertical member, so that the horizontal piece sits on it - shelf like, if you get my drift.
