There is disclosed a method of producing sealed end stringers for sliding clasp fasteners from a pair of stringer tapes, each of which is provided on one of its edges with a row of fastening elements. The tapes are first arranged so that the two rows of fastening elements face each other, and then a plurality of spaced apart pairs of strands of plastics material, which are disposed to extend transversely of the tapes, are welded to the tapes so that the tapes are connected together by the strands. The strands are severed in the region between the tapes, and a plurality of guide members of plastics material are formed on the tape edges having the rows of fastening elements, each of the guide members being connected to a respective one of the severed portions of alternate ones of the strands to extend away from the respectively adjacent one of the other strands. The tapes can then be severed between the strands of each pair so as to provide completed stringer pairs with ends sealed by the welded strands. One stringer of each such pair of stringers can be fitted with a slider and －on its guide member － with an open end box member receiving the guide member of the other stringer of the respective pair. The strand portions at the ends of the stringers remote from the guide members can be suitably adapted to limit travel of the slider along the stringers.
