Abstract
Abstract A buckle assembly formed from a molded plastic material comprises a plug member and a socket member releasably engageable therewith, the plug member having a pair of spaced engaging tongues adapted to engage with corresponding flexural flanges of the socket member to urge the flanges to displace radially outwardly beyond the confines of lateral sides of the socket member. The plug member includes a locking prong resiliently movable into and out of a window formed in the socket member. A single hand manipulation of the locking prong and/or the flexural flanges facilitates resilient release of the plug member from the socket member.
