A one-piece molded plastic clamp provided with a guiding lug for engaging a channel to prevent twisting of the arms of the clamp as they are compressed, while simultaneously enabling the clamp to be molded in a simple, clam-shell mold. The clamp includes a pair of parallel toothed members extending inwardly from one arm of the clamp and intended to engage a locking hook extending inwardly from the other of the arms. The teeth on the parallel toothed members are alternatingly spaced so that while the teeth are uniformly spaced within the plane of the clamp, they are staggered within a transverse plane so they unobstructedly face away from the plane of the clamp.

In a one-piece, molded, resilient towel clamp having two substantially straight arms and an arcuately shaped flexible portion connecting said arms, each of said arms having a jaw on the end thereof and said arcuate portion being effective to yieldingly maintain said jaws in a predetermined spaced relationship, a rack having two spaced parallel toothed members extending inwardly from one of said arms with the teeth thereon facing said arcuate portion, a locking member extending inwardly from the other of said arms and having a hook at the end thereof in alignment with and facing said rack teeth and having a guiding lug on the end thereof positioned to pass between said toothed members to maintain alignment between said rack and said locking member and to prevent twisting of said jaws under stress, said hook being adapted to mesh with one of said rack teeth once the jaws are forced inwardly against the pressure of said arcuate portion to thereby maintain said jaws in a clamping relationship, the improvement comprising: the teeth on one of said parallel toothed members being alternatingly disposed relative to the teeth on the other of said parallel toothed members such that the inner surfaces of all teeth unobstructedly face in a direction generally transverse to the plane of said clamp, said locking member extending transversely a distance substantially equal to the distance between the outer surfaces of said teeth such that said locking member will engage, at any one time, the teeth of only one of said parallel members.
