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. A resilient, deflectable bottom wall of the receptacle body deflects in response to slidable insertion of the tongue portion therein, and thereafter urges the tongue portion upwardly to facilitate locking interengagement between the raised portion thereof and the aperture in the receptacle body top wall.
