A cord fastener includes an insert having a lateral inner cord hole and provided at a lower portion thereof with elastic provisional retaining claws extending outwardly and catches for securing the provisional retaining claws; a shell having an insertion hole for insertion of the insert, outer cord holes communicating with the insertion hole and alignable with the inner cord hole, provisional retainers provided on the inner surface of the insertion hole below the outer cord holes for engaging the tips of the provisional retaining claws in a first state when the inner and outer cord holes are approximately aligned, and pushers provided on the inner surface of the insertion hole below the provisional retainers for pressing the provisional retaining claws inwardly in a second state when the insert is pressed further into the insertion hole than in the first state, thereby causing the provisional retaining claws to engage the catches so as to prevent them from engaging the provisional retainers; and a coil spring provided in the insertion hole for biasing the insert in the direction of projecting it outwardly from the insertion hole.

[ What is claimed is:] [15.] A cord fastener, comprising:an insert having a longitudinal axis, a transversely extending inner cord hole, and provided at a lower portion thereof with at least one radially movable retaining claw;a shell having an axially extending insertion hole defined therein for receiving said insert, outer cord holes communicating with said insertion hole and alignable with said inner cord hole of said insert, at least one retainer provided upon an inner surface of said shell, which defines said insertion hole thereof, at a position below said outer cord holes of said shell for engaging a tip of said at least one retaining claw of said insert, when said insert is axially inserted into said shell to a first axial position wherein said inner and outer cord holes of said insert and said shell are substantially aligned with each other, so as to retain said insert at said first axial position within said shell at which said inner and outer cord holes of said insert and said shell are substantially aligned with each other and thereby facilitate the passage of a cord through said inner and outer cord holes of said insert and said shell, and at least one pusher provided upon said inner surface of said shell, which defines said insertion hole thereof, at a position below said at least one retainer for pushing said at least one retaining claw of said insert radially inwardly when said insert is moved axially further into said insertion hole of said shell from said first axial position to a second axial position, thereby causing said at least one retaining claw of said insert to be disposed clear of said at least one retainer so as not to engage said at least one retainer and thereby permit said insert to move in an axial direction opposite to said insertion of said insert into said shell to a third axial position at which said inner and outer cord holes of said insert and said shell are not aligned with each other when it is desired to clampingly engage a cord, passed through said aligned inner and outer cord holes of said insert and said shell when said insert was disposed at said first axial position with respect to said shell, within said cord fastener; andbiasing means disposed within said insertion hole of said shell for biasing said insert in said direction opposite to said insertion of said insert into said shell and to said third axial position so as to cause misalignment of said inner and outer cord holes of said insert and said shell whereby a cord passed through said inner and outer cord holes of said insert and said shell is clampingly engaged within said cord fastener.
