A so-called rescue spreader is constructed with a pair of replaceable jaws that are mirror images of one another and are operatively positioned back-to-back. Each jaw is generally a triangle having a back side and a front side, with both sides extending from a base and converging at a tip where the sides define an included angle of approximately 20.degree. to 30.degree.. Corrugations on the back side are provided to reduce slippage. The front side along its half length extending from the tip is provided with a plurality of teeth and a circular cam is provided along the other half length of the front side.

Spreader device with replaceable spreading jaws

A shackle-type connector for the rapid attachment of a round-linked chain to an external device, such as hydraulic rescue equipment. The connector includes a body having an attachment opening which is capable of removably receiving the device, to attach the connector thereon. The chain can be extended through a chain passage hole in the body of the connector. A holding slot communicates with the hole through a transition region. A securing nose defines a chain passage channel in the transition region. The chain can be drawn through the chain passage hole, and a link of the chain is then slid over the securing nose, through the chain passage channel and into the holding slot, whereby the surrounding links, which are rotated with respect to the link in the holding slot, cannot slide into the holding slot. Thus the securing nose secures the chain in the connector.
