English to Spanish Science Agriculture Equine care

Hi all,

I'm working on the translation into Spanish (Spain) of a brochure concerning an spa for horses and in the list of features of this spa is the "quick release anti-rear strap"

This strap is connected to the horse when it is inside the spa so that it can't rear up and get over door. The sentence is as follows: Quick release anti-rear strap and 2 horse faecal collection harnesses. I just need some suggestions for the first part.

Thank you in advance for all help on this one!

Kind regards,

Christina
