Abstract: A readily burstable slide fastener 1 for an inflatable device, such as a lifejacket 101?, comprises a first stringer 3, a second stringer 5 and a slider 19 slidably mounted on the second stringer 5. At a weakened region 23 along the slide fastener 1 coupling elements 15 are omitted from each of the stringers 3, 5 so that when a bursting force is applied to this region 23 the coupling elements 15 adjacent thereto are disengaged. Coupling elements 15 are omitted from the top of the first stringer 3 so that when the slider 19 is at the top of the coupling elements 15 of the second stringer 5, the first stringer 3 can disengage from the slider 19. When the slide fastener 1 is fitted to an inflatable lifejacket 101?, the stringers 3, 5 are separated completely when the lifejacket 101? is inflated.

Each coupling head has flat sectional portions extending from center portions of one of the ends of the upper and lower leg portions toward each other, and the flat sectional portions have increasing widths. A coupling portion of the element head is sandwiched between both the flat sectional portions, is thinner than the flat sectional portions, and has tip end portions projecting toward opposite sides in the longitudinal direction of the element row. The coupling portion is reliably engaged in a small gap formed between the coupling heads and the upper and lower leg portions of adjacent elements of a mating element row. An apparatus and method for making the element row is also disclosed.
