Abstract

754,212. Band clips. MICROCELL, Ltd., and KREMER, H. March 10, 1955 [Jan. 7, 1954], No. 538/54. Class 44. A contractible circular clip of the kind comprising a closed loop, two sections of which are wrapped around a split pin 10 to form spaced bearings 11 in which the pin may be rotated and so that the two opposite portions 12, 13 of the loop on either side of the bearing sections are disposed close to one another, and a flexible length of material, one end of which is threaded through the two loop portions 12, 13 and then back against itself and the other end of which is introduced between the limbs of the split pin is characterized in that the flexible. length of material comprises a wire, for example formed from steel. The wire is wrapped twice round the hose or like to be gripped and when the split pin is rotated by a tommy bar the wire is tightened round the hose or like. The end of the wire which engages the two portions 12, 13 is bent into a hook 16 having a lateral extension 17 and the turns of the wire bear on this lateral extension and prevent the end from being pulled out of engagement with the loop portions 12, 13. The portion 13 of the loop is provided with a contracted portion 14 to keep the turns of the wire together. The limbs of the split pin may be bent to take the end of the wire or alternatively a hole 20 may be provided between the limbs. The lateral extension 17 of the hook 16 may be omitted if the contracted portion 14 is made narrow enough.
