A housing has a rotor receiving chamber with filament receiving bores lying in a plane normal to the rotor axis of rotation, a rotor being rotatably received in the chamber. The rotor and housing have complementary locking shoulders for axially locking the rotor in the chamber. The rotor has a pair of filament receiving bores aligned with the housing filament receiving bores. The rotor has an annular rib in the plane of the bores defining upper and lower rotor sections. The locking shoulders are in the lower section of the rotor and are located between the plane and the closed end of the chamber, at which end the rotor and housing have a complementary ratchet and pawl mechanism for allowing only one way rotation of the rotor relative to the housing for securing the filament to the rotor. The rib guides the filament wrapped about the rotor into sub-chambers formed by the rib to minimize blockage of the rotor bores by the locking and wrapping of one filament end to the rotor in an unlocked shipping state of the seal. This permits the free end of the filament to be secured to the other bore in the rotor at the time of sealing of the seal to an article.
