Abstract
An end-locking device for slide fasteners which enables the end of a first row of zipper teeth to be releasably locked in a socket terminal which is fixed to the end of a second row of zipper teeth. The device includes locking means mounted to pivot on the socket terminal and engaging means located at the end of the second row of zipper teeth. When the end of the first row of zipper teeth is inserted into the socket terminal in order to fasten the zipper, the locking means and the engaging means are brought into interlocking engagement with each other and held in the socket terminal. In order to unfasten the zipper, the locking means is manually pushed and this causes the ends of the rows of zipper teeth to be disengaged, thereby permitting the end of the second row of zipper teeth to be escaped from the socket terminal.
