Buckle assembly

A buckle assembly for releasably connecting three belts, comprising:

• (a) a socket for being attached to a first belt and including a hollow socket body having a pair of opposed side walls, an upper wall interconnecting respective upper edges of said side walls, and an intermediate wall extending between said side walls in parallel spaced relation to said upper wall so as to define, jointly with said side walls, and said upper wall, a guide chamber, said socket body further having a pair of retainer projections projecting from said side walls, respectively, into said guide chamber, said intermediate wall having a connected cantilevered resilient locking arm;
• (b) a main plug for being attached to a second belt and including a base portion and a resilient locking tongue extending from an end of said base portion and receivable in said guide chamber in said socket body, said resilient locking tongue being interlockingly engageable with said resilient locking arm to couple said main plug and said socket;
• and
• (c) an auxiliary plug for being attached to a third belt and slidably mounted on said main plug, said auxiliary plug including a head slidably retained on said base portion of said main plug, a pair of parallel spaced resilient locking legs extending from an end of said head and receivable in said guide chamber of said socket body, and a resilient releasing leg disposed between said resilient locking legs and extending from said end of said head in the same direction as said resilient locking legs, said resilient locking legs being snappingly engageable with said retaining projections, respectively, to couple said auxiliary plug and said socket, said resilient releasing leg having a releasing cam projection engageable with said resilient locking arm to flex the resilient locking arm against its resiliency in a direction to disengage said resilient locking arm from said resilient locking tongue.
