Door Latch kids (double) safety

cults3d

My young boy (1 year old) was getting closer and closer from being able to unlatch the downstairs door. I was kind of worried, so a morning I decided to (very) quickly design this double security for the door latch. The design is not bad, but could be better. I was quite in a hurry. I would like, first, to make sure it isn't possible to remove the elastic. Secondly, It is kind of getting annoying to have to push back on my device to "re-latch" the door. Maybe a pivoting portion (or complete system) would allow the spring loaded lock not to be in the way when reclosing the door latch. But it is not that bad. :) Hope this could help someone! I forget, I used large elastic band, but this was designed for smaller ones. I did not have any in hands at that moment. I also use double sided tape for mounting.
