Abstract
A portable two-part fastening device having a female section including a keyhole, a spring within the female section, and a ridge supported by the spring, an open channel in the female section contiguous with the narrow dimension of the keyhole, and means for mounting the female section to one part of the device. A male section comprises a button larger than the keyhole but having a width less than the open channel, with a flattened stud connecting said button to the other part of the two device. The button has an indentation on the outer face thereof of a geometrical configuration so as to mate with the ridge on the spring. The narrow dimension of the stud has a width less than the narrow dimension of the keyhole whereby the button and the stud may be positioned such that the button passes through the open slot and the stud passes through the narrow dimension of the keyhole with the spring exerting a biasing force against the face of the button hole so that the button and stud are maintained within the female portion.
