I have used Sugru for different purposes 
I used it mostly for molding around cables, replacing rubber pieces that had gotten lost etc. It is a useful tool, and remains flexible, but its adhesive capability is comparatively low: I am not sure if it is strong enough for what you want to use it for: it does not seem like it has the oomph. But I could be wrong.
Despite the usual warnings, I think that this material is less dangeorus to use than cyanoacrylics and user superglue materials.
