ABSTRACT:
A joint having improved snag resistance and peel strength is formed between overlapping end portions of a thermoplastic strap. The thermoplastic strap is formed into a loop having overlapping inner and outer end portions which are joined to one another by a resolidified thin layer of formerly melted material from each of the overlapping strap end portions. Resolidified material extends completely to an inwardly tapered end of the outer strap end portion to provide the improved joint. A resolidified mass of formerly molten material also is present in front of the tapered end to further protect it against snagging.
