Hello everyone

First off like to say Hi to everyone, I am a new beetle owner finally saved up enough and purchased my very own 1974 Beetle.

The other day while driving the clutch cable popped off the hook I am in the middle of reattaching it having some difficulty with the pedal cluster but will figure it out.

Question is, is it normal for it to pop off? Was it my driving? Is it a sign of things to come? Where can I get a better way to hook it up?

Thanks in advance.
