The invention relates to a securing pin (16) which, in order to secure two chain connector shackles (12, 14) of a chain connector (10) against becoming disengaged, can be inserted into an opening (28) formed by the two chain connector shackles (12, 14), comprising a base body (30) with a through-hole (32), at least one spring ring (34), at least two balls (36), and a securing member (38) inserted into the through-hole (32), wherein an annular groove (54) in which the spring ring is inserted (34) is provided in a lateral surface (59) of the base body (30), wherein the annular groove (54) is provided with two bore holes (66) which are aligned with the through-hole (32) and in which the balls (36) rest, and wherein the spring ring (34) has at least one leg (64) which extends in the longitudinal direction of the base body (30) and which bends out of shape if the securing pin (16) is inserted into the opening (28) incorrectly. The invention further relates to a chain connector (10) for connecting two chains formed from links and to a method for connecting two chains by means of a chain connector (10) and for securing the chain connector shackles (12, 14) of the chain connector (10) against becoming disengaged by means of a securing pin (16).

The invention relates to a load-bearing component (1) for the fastening, lashing, and/or lifting technology, such as a shackle, a snap hook, a hook, or a ring link. The component (1) comprises a plastic-metal composite system (4) which forms at least one load-bearing section (2) and at least one connection section (3). The load-bearing section (2) serves to fasten and/or suspend a load, for example, by use of a fastening device. The component (1) can with the aid of the connection section (3) be attached to an object, for example, to a load or a further component (1). In order to design the component (1) as light as possible while having a high load-bearing capacity, its is according to the invention provided the plastic-metal composite system (4) comprises a core (5) made of fiber-plastic composite (16) extending continuously from the load-bearing section (2) to the connection section (3) and comprising at least one outer shell (8) made of metal material and disposed on the load-bearing section (2) and/or the connection section (3). The outer shell (8) serves to transfer a force acting from the outside upon the component (1) across a large surface to core (5).

A coupling device comprising a flexible elongate member of at least one length of an at least twice wound rope and a pin configured to be removably engaged with the flexible elongate member, wherein the flexible elongate member is formed as a loop or a part loop completing the loop with the pin, wherein at least one winding of rope is of disparate length to at least one other winding.

A thimble apparatus for use with a rope has a thimble eye formed as a generally U-shaped shackle defining a center aperture therein with arms on opposing sides of the aperture. The thimble eye has an outer surface, a front face, and a rear face. A groove is formed within the front face of the shackle generally in the shape of a U and has a width. A rope seat is formed within the shackle beneath the groove proximal to the rear face and has a diameter larger than the width of the groove. The groove forms a passage to the rope seat from the front face along the length of the groove. A base connects to ends of the arms of the shackle closing the aperture. The base defines a channel formed as an open-ended groove through the base such that in use the channel permits a rope to extend from either one of adjacent sides of the base to position the thimble apparatus between first and second positions.

A device which can slide up and down on a chain or cable, can be loosened to attach to the chain or cable, but does not have any parts that come free when the part is loosened. The device includes first and second pieces, each made of structural material, the first and second pieces fitting together at concave and convex surfaces, to form an interlock forms inner surfaces with a through hole of a first shape that can slide along either a cable or a chain.
