Abstract: An adjustable pet collar comprises a long chain and an adjuster. The adjuster is constructed by a upper cover and seat body, in which a slit is opened on the upper cover and a slanting channel is disposed on the seat body. The chain is placed in the channel, and a sliding groove in which one end thereof is closed perpendicular to the channel is disposed at one side of the channel, and a recess groove is disposed at another end thereof. An inserting pin seat is installed in the sliding groove, and an elastic element is installed between the inserting pin seat and the closed end of the sliding groove. Whereby, the size of the collar formed by the chain is adjusted by the inserting pin seat.

Abstract: An apparatus for releasably securing an opening of a garment is described. The apparatus includes a drawstring, a casing with a window, and a cord lock. The casing has an inner tunnel and encloses the opening. The drawstring runs through the tunnel of the casing. The drawstring extends out of the casing at the window. The cord lock is located at the window inside the casing for locking the drawstring from moving into the casing when the cord lock is in a locking state, and for releasing the drawstring to move freely when the cord lock is in a releasing state. As the drawstring is tightened when the cord lock is in the locking state, the cord lock is prevented from travelling with the drawstring thereby allowing the drawstring to slide through the cord lock.
