ABSTRACT:
A fastener system for connecting and releasing two elements. The system comprises a rod-shaped product with a male part and a female part, in which the male part is sized to be receivable in the female part. Either the male or female part is provided with a screw thread and the other is provided with at least one tooth such that, when the male and female parts are assembled, the tooth is engaged with the screw thread. The part equipped with the tooth comprises a strip extending in the longitudinal direction thereof, so that when the male part is pressed into the female part, the tooth is elastically distorted axially onto the screw thread, and the tooth shape and the screw thread prevent axial movement in the opposite direction.
