Side release buckle

摘要

A buckle (10) for a collar (15) includes a plug portion (11) and a socket portion (12). The plug portion (11) includes pivotable arms (35 or 47) having lugs (36 or 50) formed on the ends thereof. A spring (40 or 55) biases the outer ends of the arms (35 or 47) away from each other. The socket portion (12) has an open end (27) and opposed side openings (28). When the arms (35 or 47) are received through the open end (27), the lugs (36 or 50) will be received through the side openings (28) to attach the plug portion (11) to the socket portion (12).
