Side release buckle fastener with semi rigid insertion structure

A buckle fastener mechanism comprising:

• a lengthwise semi rigid insertion structure having lateral, opposing ridges with an adjacent peripheral intervening protective rim,
• a receiving shell enclosure having an insertion opening and an exit opening configured to slide-ably receive said insertion structure,
• said insertion structure and said insertion opening having complementary cross sections allowing the insertion structure to be inserted into the insertion opening in only a single orientation,
• said receiving shell enclosure comprising pivoting latches resiliently and pivotably secured on opposed lateral sides of said receiving shell enclosure,
• said pivoting latches each comprise a protruding surface and a catch feature wherein the pivoting latches are secured on the receiving shell enclosure such that the protruding surface extends outward from a periphery of the lateral side of said receiving shell enclosure and the catch feature extends into the receiving shell enclosure and engages one of said opposing ridges of the insertion structure in a manner to allow a ratcheting movement of the insertion structure in an insertion direction and prevent movement of the insertion structure in an extraction direction, and
• a fastener release is accomplished through simultaneous application of manual inward force to the protruding surfaces of said pivoting latches pivoting said pivoting latches thereby disengaging said catch features from said insertion structure while also inducing an extraction force in the extraction direction on said insertion structure.
