Abstract
A tying device, including a binding strip, which has a plurality of blocking incisions on one side arranged along the longitudinal direction, and a lock head with a lead opening, having two locking plates extending from opposite inner walls into the interior, wherein the locking plates each have a plurality of locking pawls. The improvement is: The blocking incisions are arranged in two rows on one side of the binding strip, wherein the two rows are separated by a ridge. The locking pawls on the locking plates each have a slot cut in the middle so as to accommodate the ridge on the binding strip. The shape of the locking pawls fits the shape of the blocking incisions, thereby attaining a blocking effect.
