Abstract: A protective cover for temporarily enclosing a building or other structure during construction, includes a plurality of plastic or canvas panels which are mounted on cables connected to the structure, in parallel spaced apart vertical rows, by connectors including a rod for insertion through grommets in the edges of the panels, a lever rotatably mounted on one end of the rod for rotation around an axis perpendicular to the longitudinal axis of the rod, so that the rod can be inserted through the grommet and rotated to a locked position, and a C-shaped cable clamp on the other end of the rod, the cable clamp including a web mounting on and projecting perpendicular to the rod on each side thereof, an arm on each end of the web extending towards the other end of the rod and a slot in one side of each arm, the slot being inclined towards the other end of the rod and being sufficiently deep that a cable can be inserted through the slots and retained therein by the rod.
