The snare is a formed loop having ends which pass through a hollow telescoping system. The telescoping means is comprised of a main barrel connected to the loop, a slave barrel within the main barrel, and a working barrel within the slave barrel. The barrels are biased in an extended position by a spring which is connected between the main barrel and working barrel. A trigger prevents extension of the barrels and is selectively held in position by a trip. The trip is comprised of a trip sear which engages the trigger and a trip pan which forms an acute angle, preferably 30°, with the axis of the barrels. When the trap is arranged for use, the trip pan is located within the loop and an animal entering the loop and contacting the trip pan causes the trip pan and trip sear to move and release the trigger. This permits the spring to extend the barrels thereby enclosing a greater portion of the loop within the barrels and causing the loop to close around the animal forming a 270° loop. | |
