摘要： A locking device for assembling tubular frame components of exhibit framework structures and the like, including an elongated box-like housing sized to be received in a cavity of one of the frame components, the housing having an open coupling end provided with protruding spaced apart coupling ear formations integral with the housing adjacent top and bottom walls thereof and flanking the opening of said coupling end. An elongated thin spring-metal interlocking latching member is movable in the housing by a cam and has a recurved hook formation on one end thereof spanning the space between and aligned with the ear formations. An intermediate bend portion of the latch-member slidably bears against a sidewall of the housing and an integral spring leg extends angularly therefrom in inclined relation to and seated in a slot in an opposite sidewall of the housing for subjecting the bend and leg portions to tensile bending moments flexibly distorting the latching member to displace the hook formation laterally between latching and unlatching relation to an undercut recess in another of the frame components.
