Abstract: The present disclosure relates to a buckle assembled with a whistle, the buckle including: a plug member having locking arms that are formed at both ends at a front side of a base, and a guide rod that protrudes from the base at an intermediate side between the locking arms; and a socket member having a guide groove which is formed at a center of the socket member so as to be opened at an upper side thereof to accommodate the guide rod at the center, and chambers which are formed at both sides of the guide groove so that the locking arms at the both ends are inserted into the chambers, in which the guide rod is configured as the whistle.

Abstract: A strap connection member is disclosed. The strap connection member includes a pair of ring-shaped strap hangers provided at one side of a base and integrally formed so as to be spaced apart from each other. Therefore, the strap connection member may simply fix straps or connect straps such that the lengths of the straps are adjustable, and simultaneously connect two or more straps in different directions.

Abstract: Provided is a buckle including a plug member and a socket member, wherein the plug member includes lock arms and a guide rod located at a middle position between the lock arms, and the socket member includes a holder formed in a chamber so as to catch the lock arm. The guide rod is provided on the front end thereof with a holding member, and the socket member is centrally provided with a guide groove for the coupling of the guide rod and is also provided with a holding protrusion for the coupling of the holding member. As such, in addition to the coupling between the lock arm and the holder, another coupling structure is provided so as to prevent the buckle from being easily unfastened by unintentional external contact or pressure while ensuring convenient separation of the buckle with one hand as needed.

Abstract: Provided is a buckle including a plug member and a socket member. The plug member includes a plate extending forward from a lower end of a base and having a first magnet embedded in a middle portion thereof, and a holder protruding from a front end of the plate. The socket member includes an upper plate extending forward from an upper end of a base and having a second magnet embedded in a middle portion thereof, side plates formed on opposite sides of the upper plate, and a accommodation region formed inside the upper plate and the side plates so as to accommodate the plate therein. The upper plate has a holder aperture formed therein so that the holder is seated in the holder aperture when the plug member and the socket member are coupled to each other.
