A needle guard is attached to a needle hub by a polyester film strip and a needle passes through longitudinally spaced apart apertures in the strip. The film strip is housed in the needle guard in a corrugated manner. When the needle guard is pulled over the needle, the needle moves into a housing of the needle guard and into abutment with the housing while the strip is stretched between the hub and the housing to retain the housing connected to the hub under a biasing force.
