A method of molding a separable bottom stop assembly on a concealed slide fastener, including: forming a number of space portions devoid of fastener elements at predetermined intervals in a concealed slide fastener; impregnating molten synthetic resin in fastener tapes at areas around the space portion; heat-molding and hardening the tapes in such a manner that confronting edge portions of the tapes are turned over; cutting the tapes across the space portion; injection molding a second pin member of the separable bottom stop assembly on the edge portion of one tape and a first pin member of a box member on the edge portion of the other tape at the space portion, contiguously to the fastener elements; and attaching a box to the first pin member to complete the box member. The result is that a separable concealed slide fastener, which could not be put to practical use conventionally, can be manufactured simply.
