Abstract: A strap lock device has a base and sidewalls that receive a strap and a pivoting lock plate mounted on the sidewalls for engaging a strap held on the base to prevent sliding of the straps. A cam is provided to be operable to bear on and lock the locking plate down against a strap. The cam has a lever that permits one hand operation to quickly release the lock for adjustment.

Abstract: An adjustable lock for a tether line or the like, which permits one-hand operation and which is incorporated into a clamp to permit the lock to be clamped onto a support, for example, an upright column or railing on a animal grooming table, and which will permit a person to either lengthen or shorten the tether to a suitable length with one hand operation. The lock comprises a bore and an angled cross cam slot in the clamp housing. The bore carries the tether line, and the slot has a roller mounted therein. The slot has an end that intersects the bore and that will pinch or clamp the line in one direction of camming movement, and will release in the opposite direction to permit locking or release of the line by pulling the line in the appropriate direction through the bore.
