A releasable connector having two elements, one being a U-shaped member of spring metal. The arms of the U are of different lengths, the shorter arm having an inwardly extending tooth or hook portion with a recess. The longer arm has an opening. The second element is flat with a pointed end which, when it is inserted in the recess of the hook portion, spreads the arms of the U and permits the second element to enter. The second element has an opening through which the hook portion can move, completing engagement of the two. Separation is accomplished by using the second element as a first base lever to spread the arms of the first element. Pivoting the second arm in the direction opposite the separating motion allows the elements to assume an angular relationship without separation.
