Abstract: A fastening system for assembling appliances, in particular electrical appliances, comprising at least one profile rail provided with openings and comprising at least one quick-fastener which has a body in which at least one internal thread is formed, is characterized in that the body has over its length (L) at least two spaced-apart internal threads, wherein, in an exact position of the quick-fastener relative to the profile rail, each of the internal threads is brought into alignment with one of the openings of the profile rail, and in that a clamping blade having the same length L as the body is attached to the body, which clamping blade forms between it and the body a gap for receiving the profile side and holds the body against the profile rail by friction.
