Abstract: A rope clamp is provided in the form of a hook to hang on a rail, ring or other object such as a ledge. The hook may be injection moulded plastics material. Rope is lodged in a channel around the hook. The channel is wider at its mouth than at its base so that rope may be wedged or clamped in the narrow part of the channel. Guides are provided for rope entering the channel and for rope leaving the channel to bias it into the narrow part of the channel. The rope may be easily manually moved into the wider part of the channel to allow adjustment of the rope on the clamp.

Abstract: An adjustable tyer is formed using no knots. A slide, possibly made of plastics material is provided. The slide has a pair of channels through it for rope. A bight of rope is formed at one end of the slide. Anchoring means are provided to anchor the rope so that it is fixed against sliding in at least one of the channels. When rope is fixed with respect to only one channel a slip noose is formed. When rope is fixed with respect to both channels a tyer of fixed length is provided. The anchoring means to fix rope in respect of the second channel is releasable for adjustment purposes.
