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 connecting device of a retaining ring of a safety belt includes a main body, a bolt, and a locking member. The main body is used with the bolt to form an enclosure or not. The bolt passes through a bolt bore of the main body and has a first teeth portion and a stopper located in a first half part of the first teeth portion. The first teeth portion and the locking member are used to control the bolt to lock or to unlock. The locking member could move between a first position and a second position along an axial direction of the locking member and could rotate around a central axis of the locking member. When the bolt is at a closed position and the locking member is at the first position, a second teeth portion of the locking member is meshed with the first half part. When the bolt is at the closed position and the locking member is at the second position, the second teeth portion is meshed with the second half part.

A securement device is disclosed to aid in the movement or suspension of equipment or people through the air or along inclined surfaces using rope, cable, wire, or similar component and associated lifting, winching, lowering devices, mechanical advantage systems or manual power by retaining a system component between a yoke and a load pin using a load pin assembly. The load pin is biased into a locked position through the use of a biasing member but may be moved from a locked position to a retracted position by journaling a lock pin through a lock slot. Some embodiments restrict movement of the load pin using a track pin and a track slot, while other embodiments use the interaction of a lock ring and a keyed recess formed in the yoke. The securement device may be incorporated as part of a rigging plate.

Improved latches for overhead corners which reduce the susceptibility of bundled frame components becoming unlatched and separated due to insufficient torque of latch knobs or to repeated shock. The improved latches retain the prior art notched latches along with their strength and simplicity, but are capable of absorbing shock by accommodating a rotational dynamic present in a latch-to-strike connection rather than attempting to prevent it. One of two styles of moveable, pressure-actuated latch keepers is joined to a notched latch of an overhead frame. One style of keeper provides a barrier into the latch's notch, while another style of keeper provides a barrier relative to the strike's features. The latch keepers provide a predetermined amount of resistance to a radial force applied to the latch. This force retains the strike into the latch's notch in a fully-seated orientation, yet allows for the beneficial shock-absorbing rotational movement of the latch to the strike. This use of pressure-actuated keepers eliminates the need for the prior art latch knob and thus also eliminates the subjectivity associated with determining the proper degree of torque required to sufficiently secure the latch to the strike under a range of conditions.
