To obtain a tire anti-slip device including an anti-slip body having a tread portion making contact with the ground, inner and outer link portions formed to protrude respectively from the tread portion to the tire inner and outer sides, and a tightener configured to tightly fit the body to the tire, and can prevent removal of the body from the tire inner or outer side direction in the tightener operation so that the tire anti-slip device can be mounted to a tire optimum position with a simple manipulation, a wire guide portion capable of guiding the tightening wire in the body width direction is formed in a position of one end portion of the body, and one end position (of the wire guide member) and the other end position of the body approach each other in both positions of the inner and outer link portions by tightening the tightening wire.

A locking carabiner includes a body having a first end and a second end. A gate rotatably coupled to the second end about a gate axis, and a locking mechanism rotatably coupled to the gate about a locking mechanism axis. The locking member is configured to engage with the first end, and the gate axis is substantially parallel to, and offset from, the locking mechanism axis. Additionally, the rotation of the locking mechanism is in a substantially similar plane as the rotation of the gate.
