How can I secure a door latch blocker without drilling?

Question

I have a door latch cover that looks like this:

Its installed in a common area so I cannot drill any holes. Right now its attached to the door with an elastic band as shown in the photo but they keep stretching out so I constantly have to replace them. What could I use instead of an elastic band to make this more or less permanent? First thing that comes to mind is to use a metal wire but how do I connect the two free ends after cutting out a big enough piece?

Many years ago I've seen a small metal connector used on a clothesline where you put two ends of the cable inside and then used the screw to make the rope tight, but I can't remember what it was called and can't find it in Google. Something like this would be perfect for my purposes.

Answer 1

Use cable ties instead of the elastic bands.

Answer 2

if you want to use wire bend both ends of the wire round the anchor tab of the blocker.

I worry that wire might mar the door handle, something soft like string or parachute cord might be a better choice. You may need an assistant to help you tie the knot.

Answer 3

I had a similar problem and I found that simply putting a flat metal plate over the strike plate offered free access. This is a more permanent solution as if you want the door to lock our stay closed occasionally you would have to remove the metal plate to accomplish normal use.
