Abstract
A leader-pin to securely hold the leader of a film strip or magnetic tape for high speed unwinding and rewinding wherein the end of the film strip or magnetic tape is inserted between a split rod and the split rod is then inserted into an elongated, resilient tube, with the end of the strip protruding from an elongated slit in the tube; the tube frictionally engaging the strip and the rod, so that the strip will not slip out of the leader-pin.
