Abstract: A vibration resistant fixing or securing means, for fastening or securing a first member to a second member, comprises a resilient bush gripping one of the said members and having a fastening stud, carried by the other of the said members, extending through it. The fastening stud and the said first member are so shaped as together to constitute a compression stud assembly comprising a male part and a female part, which are adapted to be locked together and to extend through an opening formed in the second member and resilient bush, the latter comprising a boss having one free end portion with a radially projecting portion at its other end, and the compression stud assembly including a shoulder and a flared portion, which cooperate to maintain the free end portion and radially projecting portion of the bush respectively in gripping contact with edges of the opening in the second member.
