Abstract: A molded plastic buckle adapted to releasably secure extremities of a web-like material includes a receptacle body and an insert body having a tongue portion adapted to be slidably received in the receptacle body. The receptacle body includes a top wall having a through aperture defining a plurality of surrounding side surfaces. At least one of these side surfaces is angled to converge in the direction of slidable insertion of the insert body tongue portion. The insert body tongue portion includes a raised portion receivable within the aperture. This raised portion has a trailing side surface formed at a complementary angle to the angled side surface of the aperture to facilitate locking interengagement between the raised portion and the aperture.

Abstract: A clip assembly for securing abutting edges of roof deck panels together and to an underlying support structure in such a manner as to conceal the clip assembly and permit relative longitudinal movement of the panels to the support structure responsive to forces from thermal expansion or contraction. The clip assembly comprises a clip member and a foot member slidably interconnected by a hook on the foot member which is received in an elongate slot formed in the clip member. The clip and the foot interconnection includes means to center the two members relative to one another.
