Patent attributes
A connector pin includes a stem extending between a head and an opposite foot. The stem includes a neck having a plurality of sections which may be planar forming edges. A retention member including a collar and arms extending therefrom is retained around said pin, the inner surface of the collar correspondingly configured to the sections and edges of the neck for a frictional fit. The pin is insertable and retained within a receiver in overlapping mats. Pockets in the receiver hold the retention member arms and prevent rotational motion of the retention member. The pin is selectively movable relative to the retention member by rotational motion by application of force to the pin sufficient to overcome the threshold level of friction holding the sections of the neck at the collar. Locking the pin is achieved when extension members of the pin foot are misaligned with the retention member arms.
