An improved buckle includes a plastic shell, an inserting element, and a lock core. A horizontal socket fitting with the inserting element and a cylindrical mounting slot for mounting the lock core are formed on the plastic shell, the cylindrical mounting slot communicating with the horizontal socket. The horizontal socket includes a guiding block, and the inserting element includes an inserting piece for inserting into the horizontal socket to cooperate with the lock core, with two triangular notches symmetrically and a guiding groove cooperating with the guiding block formed thereon. The buckle has advantages of a simple structure and a reasonable design, and may realize the dispersion of the strength by utilizing the special structure of the lock core, so the structural strength gets ensured, and meanwhile the buckle may be kept light-weighted, and thus the buckle is suitable for the pet industry.

An adjustable-length tensile member, for example, a strap for a wearable pack, can include a fastener member defining first and second apertures and a cross-member positioned therebetween. A strap can extend through the first aperture in a first direction, over the cross-member and through the second aperture in a direction opposite to the first direction. A cover plate can matingly engage with the fastener member to obscure a segment of the strap from view. Wearable packs can incorporate such adjustable-length tensile members. Methods for assembling such adjustable-length tensile members are also disclosed.

A method for forming a double-sided loop strap includes: receiving a continuous longitudinal strip of loop material including a strip-form base bearing a field of upstanding loops on a fastening side of the strip bounded by opposite longitudinal edges, folding each of the longitudinal edges away from the fastening side, such that the base overlaps itself, and securing the folded edges in place by permanently bonding together overlapped areas of the base to form the double-sided loop strap.

A band connector which is adapted to fix a folded band is disclosed, and includes a buckle and a cord. The buckle has a first connecting portion, a second connecting portion, and a junction, wherein the first connecting portion and the second connecting portion are connected to two bands respectively. The cord is provided on the junction for fixing the folded band. In addition, the band connector is applied to any band, such as a leather belt, a strap of a backpack, and a waist belt. After the length of the band is adjusted, the redundant segment of the band can be folded and bundled by the cord.
