<p>A U-shaped clip intended to be deformed to enclose and close the mouth of a flexible tube or bag, comprising a pair of limbs of substantially constant cross-section and a web joined to the limbs, respectively at a pair of transition points, the cross-sections of the web and transition points differing from and having a higher section modulus than the cross-section of the limbs. Advantageously the limbs are round in cross-section and the web at the middle is rectangular with rounded corners, the web changing in cross-section gradually from the middle to the transition points. Indentations may be provided on the outside of the limbs near their ends to facilitate buckling of the limbs toward one another when the clip is worked upon by a closing tool. The clips are assembled one behind the other with their limbs forming two parallel lines, constituting a magazine for supply to the closing tool.</p> |
