Patent ID: 7883288

Claim:
A connector assembly, comprising: a hollow frame member having a deformable open end, a projection dimensioned such that force is applied to fit the deformable open end over the projection; an outer surface of the first side wall of the projection having a first plurality of ribs an elongated projection having a first side wall and a second side wall resistant to deformation connected by an end wall configured to resist lateral movement of the first wall and the second wall; an outer surface of the second side wall of the projection having a second plurality of ribs the outer surface of the first side wall and the outer surface of the second side wall each having an orthogonal length perpendicular to a longitudinal length of the projection, the orthogonal length being greater than a length of a first internal surface and a second internal surface of the hollow frame member such that when force is applied to fit the deformable open end over the projection in a direction along a longitudinal axis of the elongated projection, the first and second internal surfaces of the hollow frame member stretch to the orthogonal length of the projection and the first and the second plurality of ribs positively engage the first and second internal surfaces of the hollow frame member, respectively.
