CLAMPING SPRING COLLAR WITH IMPROVED SAFETY

摘要

A spring clamping collar constituted by a rolled-up metal strip (1) with the end portions (1a-1b) of said strip each being of a width that is substantially equal to half the width of the strip, said portions being disposed beside each other and being provided with tabs that extend radially outwardly from the collar, thereby forming abutments for engaging a pliers-like tool. Each tab extends over substantially the entire width of the strip and possesses, on its side remote from its connection to the corresponding end portion of the strip, an extension (2a-3a) which extends over the other end portion of the strip and is directed away from the tab carried by said other end portion.
