Claim:
A slide fastener with a reverse opening separable end stop, comprising: a fastener chain on which two sliders are mounted with rear ends thereof opposed to each other, the fastener chain comprising a pair of right and left fastener stringers on which a plurality of fastener elements are attached in a row along opposing side edges of two fastener tapes; and the reverse opening separable end stop comprising: a box pin attached to one end of a row of the fastener elements of one of the fastener stringers; and an insert pin attached to one end of a row of the fastener elements of the other one of the fastener stringers, wherein: one of the two sliders comprises a reverse opening slider into which the box pin and the insert pin are configured to be inserted, the insert pin comprises a contact portion that is configured for contacting a locking pawl, the locking pawl being provided inside the reverse opening slider so as to extend from a top surface of the slider and into and out of an element passage inside the slider, the contact portion projects from a part of a side surface of the insert pin in a direction toward the box pin, and the contact portion comprises a notch portion formed in a step-like fashion from a corner portion in which the front end portion of the contact portion on a side opposing to an element side and the side surface of the insert pin in a direction toward the box pin intersect to a front end on a free end side of the insert pin, and the notch portion allowing the locking pawl of the reverse opening slider to invade therein when the insert pin is inserted into the reverse opening slider, and when a side surface of the contact portion on a free end side of the insert pin comes into contact with the locking pawl, the side surface of the contact portion prevents the reverse opening slider from moving on the fastener chain toward the opposing slider.
