Abstract
Encircling clamps of a flexible elongated body fitted at a first end with a pair of parallel arms encircling a bay open at their extremities, and at the other end with a tongue that is insertable into the bay. One arm of the bay is a spring having restoring force when flexed away from the other arm, and ratchet teeth on its inner surface extending only part way from the opening to the interior of the bay. The tongue has mating ratchet teeth extending a longer distance so that when the tongue is inserted into the bay it can be adjustably positioned therein while engaging all the ratchet teeth of the spring arm. The closed device can be opened by lifting the spring arm away from the tongue. Means are provided to pull the tongue into the bay.
