A connector pin assembly is insertable into aligned openings in telescoped ground engaging wear and support members to releasably hold the wear member on the support member. The assembly has a tubular outer housing that is nonrotatably received in the openings. A connector pin longitudinally extends through the housing and is rotatable relative thereto among selectively variable rotational orientations in which the pin is releasably locked to the housing by cooperative detent structures carried by the housing and the pin. Outer end portions of the pin perform two functions which are controlled by rotating the pin relative to the housing. First, outer pin member end portions are rotatable to selectively hold the wear member on the support member or release it therefrom. Second, the outer pin end portions are rotatable to adjustably tighten the wear member onto the support member.
