PROBLEM TO BE SOLVED: To provide a separable bottom end stop preventing a reinforcement portion having flexibility from being damaged by scattering an external force applied to a reinforcement portion upon the opening/closing operation and reducing an applied load thereby. SOLUTION: This slide fastener is so formed that reinforcement portions 10 are formed on a lower half of a box pin 8 and an insert pin 9 of the separable bottom end stop 5 with synthetic resin symmetrically on both front and rear surfaces of a fastener tape 3 such that the reinforcement portions are extended on the fastener tape 3. Each of the reinforcement portions 10 is constituted of an inside portion 11 adjacent to the box pin 8 or the insert pin 9 and an outside portion 12 connected thereto. In the inside portion 11, a plurality of ribs 13 are disposed obliquely and concave portions are formed among the ribs 13 so as to supply flexibility. The outside portion 12 is formed of thick ribs 13 such that it is connected to the inside portion 11. Consequently, an external force applied to the reinforcement portion is scattered by the oblique ribs 13 in the thin inside portion 11, thereby reducing the applied load.
