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. 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 grooves have overhanging lips which detachably retain the studs in place. The paper in thus securely bound. To prevent cracking the studs, the abruptness of the 90.degree. bend may be relieved by forming an annular depression around the base of each stud.
