A connecting device for connecting a table leg to a table leaf having a back-gripping element, which can be disposed on the table leaf and has an engagement hole and a locking device, which can be disposed on the table leg. The locking device has a clamping element having an engagement hook which is designed to engage the engagement hole of the back-gripping element, a spring element, which is supported at least indirectly against the clamping element and at least indirectly against a spring abutment, and an actuating element. The actuating element acts on the spring abutment so that, in a locking position, the spring abutment applies sufficient force to secure the engagement hook of the clamping element in the engagement hole, and in an unlocking position, the spring abutment is in a position in which the spring element is at least partially unloaded in relation to the locking position.

A fastener for releasably securing a member comprises a body including a shank and a recess, the recess configured for receiving the member. A gate is mounted to slide axially on the shank between a closed position closing a mouth of the recess for retaining the member, and an open position. Resilient means engages the gate and the shank to urge the gate to the closed position, and latches are mounted on opposing sides of the gate, wherein each latch is self-closing and engages the body for holding the gate in the closed position providing an auto-locking fasteners that for greater security requires three independent actions for release.

A hook formed into a body formed into a hook shape and having a neck and fabricated from nonferromagnetic material with the body having a first end and a second end. The neck is proximate the first end. One side of the neck includes a center ridge with a flat top surface with either a magnet or ferromagnetic material embedded in the center ridge. The hook also includes a closure having a first closure end and a second closure end and a channel with a floor flanked by two lateral sides. A second magnet or a ferromagnetic material is embedded into the floor opposed to the first magnet or ferromagnetic material. The closure being pivotally and/or pivotally and slidably attached to the hook body by at least one pin. The magnet(s) and/or ferromagnetic material hold the closure in a closed position enclosing a defined space.

A suspension device has a base plate (11) intended to be fastened to a wall and two rods (15, 16) fastened on the base plate with the ends pointing towards one another. The rods have end knobs (17, 18) and one end knob (18) is spring-loaded to rest against the end knob of the other rod. Using a closed loop, a snare is made around the object that is to be hung up and then the loop is pressed in between the ends of the rods so that the loop remains hanging on one rod. The cord can simply be pulled loose by pulling it out between the end knobs when it is desired to detach the object

A connector for use with a fall protection system includes a body, a gate, and a double action locking mechanism. The body includes a spine and two arms extending from the spine to form a gate opening, the arms defining axially aligned first and second apertures respectively. The gate is adapted and configured to move axially through the first and second apertures. In an open position, the gate extends through the first aperture, but a forward end of the gate is spaced rearwardly of the second aperture. In a closed position, the gate extends through the first aperture and the second aperture. The double action locking mechanism is adapted and configured to require application of two distinct and different forces to unlock the locking mechanism and permit the gate to move to the open position.

An assembly for rotating a workpiece including a locking side pull hoist ring removably attachable to a side surface of the workpiece. The locking side pull hoist ring comprises a load bearing structure, a rotation mechanism attached to the side surface of the workpiece that rotates about a rotation axis extending through the rotation mechanism, a locking mechanism configured to transition between a locked state and an unlocked state, and a support member connecting the load bearing structure and the rotation mechanism. The support member rotatably supports the rotation mechanism for rotation about the rotation axis and rotatably supports the load bearing structure for rotation about a second axis. In the locked state, the locking mechanism prevents rotation of the rotation mechanism by securing the rotation mechanism to the support member.
