Tudor strap (leather) fail

[stropley]

Hi I have a Tudor Grantour that I've had a couple of years but don't wear all that often, especially if I think I'll get wet or sweaty, due to the leather strap. However now the leather is coming away from the metal strap end which attaches to the watch.
From the photo what'd be your advice? The strap is in otherwise perfect condition, can it be glued back together or do I need a new strap (or half strap if you can buy such a thing)? Thanks for looking.
