A method for making a repair to a repair site of a structure made from at least a first tube and a second tube which are joined together with welds. The method includes cleaning and preparing the at least first tube and second tube tubes at the repair site for bonding with composite repair materials. Next, fiber-reinforced polymer composite repair materials are applied to the repair site. These composite materials include at least one elongate, composite tendon strip which is placed on the at least a first tube and a second tube such that the composite tendon strip bridges at least the first tube and a second tube, and a composite strip which is wrapped around and overlays the tendon strip with additional composite strips. The invention also provides a metal structure reinforced with a composite material repair site according to the method.

A wrapped and curing substrate is secured: with a strap. The strap has two clips, each having a prong. The prong of a first clip is slid in a first direction into a first portion of the wrapped substrate. A second clip is pulled away from the first clip over a substrate edge, and the prong of the second clip is slid into a second portion of the wrapped substrate in a direction opposite the first direction. In one embodiment, the first portion of the wrapped substrate is an overlapping layer of substrate, and the second portion of the wrapped substrate is the layer of substrate extending from underneath the overlapping substrate.
