Abstract
A top end stop of one of opposed fastener stringers of a separable slide fastener has an obtusely angled configuration composed of longitudinally continuous and integral first and second half parts. Each of the first and second half parts has a maximum width equal to or slightly smaller than the width of each branch of a Y-shaped guide channel of a slider so that the top end stop can pass through the guide channel branch as it is moved in a C-shaped path. The top end stop has a maximum width, as measured perpendicularly to an inner longitudinal edge of the tape, larger than the width of the guide channel branch, and hence cannot pass through the guide channel branch as it is moved simply in a straight path.
