shower faucet leak

[shark24]

What can i do? Leaking at the point of the hose from the shower held hose part that connects the hose to the wall box looking piece. Seems like it could just be tightened or a new o ring, replaced but since it is all plastic, I didn't want to start messing with it because it is working fine for now but thought it is probably reducing the amount of water pressure on the head which would probably work better if is was fixed.
Thanks for your thoughts!

No problem with tightening it a bit. That will probably fix it. Finger tight is usually enough, but putting a piece of cloth on the fitting (to avoid scratches) and giving it a quarter turn with pliers won't hurt. If by chance the hose or o-ring are the problem, the hose is a very inexpensive part that can be bought at any hardware or big box store. Try those ideas first.

My shower leaked as well.  It took me a while to find the problem.  The shower diverter tee was busted.  My guess is that the dealer did not drain the lines the previous winter, and that the frozen water cracked the diverter tee.  The water was leaking within the faucet diverter box that holds the knob handles.  Water was leaking inside the wall, and coming out the bottom of the camper.  My wife noticed it while I was showering. 

I replaced the part with something like this:

You need to unscrew the diverter tee box and replace the caulk when you are done, but it's not too hard to do.
