Slide of auto-lock zipper

An automatically locking slide for a zipper comprising:

• (a) a main body having top and bottom plates defining therebetween a pair of longitudinally extended sliding grooves, said top plate having a through hole formed therein;
• (b) a tab coupled in substantially pivotal manner to said main body, said tab being displaceable about a pivotal end portion thereof responsive to user actuation;
• (c) an elastic plate coupled to said main body, said elastic plate retentively engaging said pivotal end portion of said tab, said elastic plate including a longitudinally extended fastener portion, a longitudinally extended distal bent portion, and an arcuate proximal bent portion extending integrally therebetween, said fastener portion being spaced from and extending at least partially over said distal bent portion, said distal bent portion having an arcuate section terminating at a clamping unit, said arcuate section having a first surface and a second planar surface thereof, and a lengthwise groove formed at said first surface of said arcuate section, and extending within the thickness of said arcuate section defined between said first surface and said second planar surface thereof and along substantially the whole length of said arcuate section;
• said elastic plate being elastically biased to a first configuration, whereby said clamping unit thereof extends through said top plate through said through hole of said main body into at least one said sliding groove, said elastic plate being deflectable responsive to user actuation of said tab to a second configuration, whereby said distal bent portion is displaced relative to said fastener to substantially withdraw said clamping unit from said sliding groove of said main body.
