A releasable touch fastening includes a fastener strip (2) and a retention bead (20). The fastener strip includes two parallel rows (6) of opposing closely spaced fastener elements (8) extending from a common base (4) to form a retention channel (10). The two rows are separated by a small distance to receive and capture the retention bead constructed to fit between the fastener rows and under the heads (14) of the fastener elements.
