2094240 9304260 PCTABS00020 An inflatable packer (16) includes an elastomeric tubular body (22) and an outer cover (24) surrounding the body (22). An end member (30) is also provided having a capped portion (32) threadably engageable with an annular ring member (34), the ring member (34) being secured to the end portion (36) of the outer cover (24). A plurality of reinforcing elements (28) are sandwiched between the cover (24) and the body (22) and have end portions (54) terminating beneath the ring member. Finally, there is a mechanism (60) for wedging the end portion (54) of the reinforcing elements (28) against the inner surface (66) of the ring member (34) in response to increased threaded engagement between the capped portion (32) and the ring member (34) to retain the elements (28) in position beneath the ring member (34).
