A device for tying cable bundles including a plastic tightening strap of indeterminate length having transverse ribs and a separate locking piece also of plastic, having an orifice for receipt of two thicknesses of the tightening strap and two tongues which project into the orifice and interact with the transverse ribs on the strap. The tongues, each of which carries at least one engaging tooth, are formed of inner walls of the locking piece opposite one another so that they can flex open to permit the strap to pass through in one direction, but which spring back to prevent the strap from passing back through in the opposite direction.

A cable tie comprising a tightening strap of indeterminate length having a plurality of transverse ribs on at least one longitudinal surface thereof and a separate locking piece having a housing, an orifice in the housing through which two ends of the tightening strap can pass, and locking means projecting into the orifice from opposite sides of the housing for interacting with the transverse ribs, each of said locking means having at least one engaging tooth that operates in a first locking direction for engaging a rib of one end of the strap and preventing it, when engaged with a tooth, from passing through the orifice in the opposite direction, the gap between the teeth being larger than the thickness of the strap, but smaller than double the strap thickness less the height of a rib, with at least one of said locking means being resiliently connected to the housing so that it can flex open to permit one end of the strap to pass through the orifice in said first direction but will spring back to engage its tooth with a rib of the strap to prevent it from passing back in said opposite direction.
