Yep. That’s what they are: love locks. Wikipedia even has an article about them as they do present something of a nuisance at times. Apparently the locks are something like humans. Once they have a foothold, they multiply and take over. Clearly something must be done and soon. Perhaps playing on an endless loop Meatloaf’s “Paradise by the Dash Light” would be a prophylaxis…
