ABSTRACT:
A roof system comprises roof support members, such as rafters and purlins, to which truss members are connected. These members are formed as sheet metal beams. The truss members are joined to the other members by spring truss pins or clips. These clips are generally formed as a spring bight having first and second legs, with key portions formed at the free end of the legs. The key portion of the first leg includes an indentation which faces away from the second leg, and a short stub member. The second leg key portion includes an offset which extends transversely in the direction towards the line of the first leg, and a stub member which extends in the direction generally parallel to the second leg.
