A fastener for securing together articles, such as pull-tabs of a zipper, includes a gate arranged to slide in a channel in a body between a closed position, in which the gate closes the mouth of a recess in the body, and an open position, in which the mouth is open. A fixture at one end of the gate is provided for connecting a tether. A latch member prevents the gate from sliding from the closed position when in the locked position and is resiliently urged to the locked position and configured so that, in use, the latch member is pressed and moved to the unlocked position when a user grasps the body and, in the unlocked position with a tether connected to the fixture, tension in the tether tends to slide the gate to the open position.

The invention discloses a safety lock catch, which comprises a lock body, a lock bolt, a force component and a thumb wheel; the lock body comprises a mounting portion and a hook portion, the hook portion has a first end and a second end, the first end is connected with the mounting portion, the second end is bent toward the mounting portion and there is a gap between the second end and the mounting portion, and a chamber is provided in the mounting portion; The thumb wheel is pivotally connected with the mounting portion, the thumb wheel is engaged with the lock bolt, and the lock bolt can be moved from the first position to the second position by the drive under the thumb wheel. The safety lock catch provided by the invention is not easy to fall off when used, and has better safety.

A self-closing and locking device for hanging objects on a mounting surface is disclosed. The device includes a mounting bracket and a locking arm member translatably engaged with an elongated track portion of the mounting bracket. The track portion comprises a pair of guide portions defining a slot therebetween, and rear recesses in a back side of the guide portions. The rear recesses comprise lower locking portions, and upper rotating portions that are deeper than the locking portions. The arm member comprises a base portion that is positioned within the rear recesses, and an arm portion that extends from the base portion and through the slot. The device is configured such that the arm member is oriented in a closed position when the base portion is engaged with the locking portions, and orientable in an open position when the base portion is engaged with the rotating portions.

Connectors for coupling fall arresting devices to a safety harness. The connectors may include a first pin configured to lock into a first side of a base portion using one or more locking mechanisms. The first pin may be used to engage with one or more fall arresting devices to attach the one or more fall arresting devices to the connector. In some such examples, the locking mechanisms may be positioned within interior portions of the first side of the connector so as to allow the one or more fall arresting devices to pivot freely about the ends of the connector. In some examples, the connectors may include a second pin configured to lock into a second side of the base portion using one or more locking mechanisms. The second pin may be used to conveniently and releasably attached the connector to a safety harness of a worker.

The anchoring device for shuttering walls includes a body containing an arm with a top tab, a fastening part for at least one connector, a moving closing part mounted in the body and pressed to the closed position at rest, and a locking part. The closing part is a sliding part with an indentation on one of its lateral surfaces which is matched with the slider lock in the open position of the device, and with pass-through pockets and a bottom tab, forming, together with the arm and the upper tab of the body, a tong closure assembly. The device has a set of springs, of which one pushing spring is located inside the body directly above the slider lock and is secured from above by a pressure screw. The three compression springs are located inside the body in the pass-through pockets of the slide.
