Abstract
A pair of strut members are pivotally attached on either side of a dolly used to pivotally couple the front of a trailing trailer to the rear of a leading trailer. The struts are pivotal between an opened or in-use position in which any substantial pivotal movement of the dolly about relative to the leading trailer about a vertical axis is prevented and a closed or out-of-use position in which free pivotal movement of the dolly relative to the leading trailer is allowed.
