Abstract
Abstract An apparatus for securing one or more small diameter conduits to a larger diameter tubing string in an oil well and comprising a metal band encircling the tubing string and the conduit with a wedge-type lock for securing the opposite ends of the band together thereby securing the conduit to the tubing string. One or more conduit receiving corrugations are formed in the band. In one form, the apparatus includes a rubber liner interposed between the band and the tubing string. In another form, dimples are formed in the band to engage the tubing string. In yet another form, the band is divided into two segments connected by a hinge. In still another form, two separate band segments are connected by two wedge-type locks.

Claim 4
Independent Claim
292 words
An apparatus for securing a small diameter conduit to a larger diameter tubing string having sufficient strength to withstand strain in a turbulent environment and which can be readily installed or removed from said tubing string or the like said apparatus comprising: a band formed of thin gauge sheet metal having a first end and a second end and encircling said tubing string with the first end adjacent to said second end thereof; a first connecting means formed on the first end of said band for connecting the first end to the second end of said band; a second connecting means formed on the second end of said band dor connecting the second end to the first end of said band; a locking means engageable with said first and second connecting means for urging said first and second connecting means relatively together and locking said band securely to said tubing; each of said connecting means having a plurality of locking means engaging surfaces formed so that said surfaces and locking means have an angular relationship such that the locking means and surfaces progressively engage to releasably secure said band to said tubing string by a uniform wedging action to minimize the possibility of interference with adjacent tubing strings; there being at least one pair of locking means engaging surfaces on each end of said band in alternating spaced relation so that the surfaces on one end of said band mesh with the surfaces on the other end of said band; and a conduit receiving means formed in said band for receiving said conduit between said band and said tubing string whereby said conduit is secured to said tubing string when said locking means is locking said band securely to said tubing string.
