An improvement for the structure of end hook for the tape measure consists ol a u-shaped flexible elongated metal folder and a conventional end hook. The U-shaped flexible elongated metal folder, having a slim parallel gap which is slightly greater tha n the thickness of the metallic tape, sandwiches the tape therebetween at the outer end of the t ape below the end hook. At the outer edge of the tape, there is a rectangular notch, whose depth is equal to or a little greater than the the; kness of the end hook. The flexible e longated metal folder is longer than the end hook, with the closed end thereof engaging the sai d rectangular notch, so that there is an extended portion stretching beyond the inner end of t he end hook. The conventional end hook is mounted on the said metal folder and the tape, over lapping with the metal folder and the tape, then all these three elements are riveted to gether. The extended portion of the metal floder without overlapping with the end hook is ri veted with the tape only. The reinforcement with the additional U-shaped flexible elongated metal folder improves the structure of conventional end hook in enhancing considerably the strength to withstand the stress of impact, forfending the usual disadvantage of fracture or rupture of the tape and rivet failure.
