1. A universal joint (200) for securing a wheel chock (100) at a free end (154) of an arm assembly (152) in a wheel chock handling unit (150), the joint (200) including:
a proximal section (202) having a main axis (204) and a lateral side;
a distal section (206) affixed to the lateral side of the proximal section (202), the distal section (206) including:
a main plate (220) defining a first plane (226) projecting from the lateral side of the proximal section (202);
a first pivot coupling (208) provided on the main plate (220) and defining a yaw axis (210);
an elongated link (260) attached to the first pivot coupling (208) and being pivotable about the yaw axis (210) with reference to the main plate (220), the link (260) having a main axis (212) and having a free end positioned away from the lateral side of the proximal section (202); and
means for limiting axial pivot movements of the link (260) within a range of angular positions having a first angular end position and a second angular end position.
