Abstract
A first plastic strip has longitudinally spaced studs each of which can be bent over at a 90.degree. angle. A second strip has holes through which the studs fit and grooves which receive and secure the bent over studs. Several stud shapes and bent stud retaining grooves are described. Paper punched to receive the studs is clamped between the two strips. The studs are then bent over into grooves in the second strip and held in bent position. The paper is thus securely bound. A channel may be slipped over the outside of the second strip to conceal the bent studs and further secure them in place.
