Abstract: A plumbing fitting (100) has a cap (1) and a body (3). The body has a fitting end (5). Engagement projections (7, 9) extend radially outwardly from an outer circumferential surface of the fitting end (5). The cap has a first tab (13) and a second tab (15) with free ends. The tabs (13, 15) have receivers (23, 25) to receive the engagement projections (7, 9). The tabs permit flexure of each tab relative to the other. Each tab has a radially inwardly extending spacer member (27, 28, 29, 30) at the free end of the tab. As the fitting end is received by the cap, the free end of each tab is displaced radially outwardly to space apart an inner circumferential surface of the tabs from the outer circumferential surface of the fitting end, thereby providing clearance for receipt of the engagement projections (7, 9) by the receivers (23, 25).
