In a hook fastener having a sliding closure for closing the mouth of the hook, a keeper prevents opening of the closure. The hook fastener includes a body having a base portion and a hook portion extending from an end of the base portion to define a gap between the hook and the base portion. An opening formed in the base portion has an elongate mouth intersecting an external face on the base portion. The closure includes a shaft part and a grip part, the shaft part received in the opening, the grip part protruding from the shaft part through the mouth for manipulation by a user. A spring urges the closure such that the shaft part extends out of the opening into the gap. The keeper is received to rotate upon the external face, being located between the grip part and abutment on the body. A slot in the keeper extends parallel to the mouth, the keeper preventing the user retracting the closure from the gap, except when the slot is rotated so as to be angularly aligned with the mouth.
