A sliding clasp fastener comprises a slider 3 and two coupling strips 1, 2 each symmetrical relative to a common longitudinal plane, one coupling strip 2 being shaped in cross section to provide an anchor and a U-shaped securing part 8 having arms 9 extending parallel to a stem 12 of the anchor and projecting towards the anchor head 10 to which part 8 the anchor is connected by its stem and the other coupling strip 1 being shaped in cross section to provide a pincer part with arms 5 adapted to engage around the anchor head at least the coupling strip 1 being made from yieldable resilient material, the free ends of the arms of the securing part being chamfered away from the anchor stem and anchor head and the free end portions of the arms of the pincer part being of Z shape including offset parts 7 having portions 7<SP>11</SP> adapted to engage in the spaces between the arms of the securing part and the anchor stem and the arms 5 being chamfered to match the chamfers of the arms 9 of the securing part, the slider comprising a housing 13 which surrounds the securing part and the anchor on one coupling strip and the pincer part on the other coupling strips the housing having in its interior a guide 14 for engagement around the head of the anchor and which upon separation of the coupling strips serve to disengage the Z-shaped arms from the anchor and withdraw the portions 7<SP>11</SP> of the offset parts from said spaces. The strip 1 is made of a flexible resilient synthetic material such as polyvinyl chloride, polyethylene or rubber and the strip 2 is either made of this flexible material or is made of a material such as aluminium.
