Abstract: A connection assurance bracket system (100) which is interfaced between mutually interconnectable first and second connectors (108, 118) to provide assurance of the connection therebetween and eliminate relative motion therebetween. A connection assurance bracket (102) has a flattened horseshoe-shaped base (104) defining a rectangular cut-out (145), wherein a cantilever beam (106) projects normally therefrom. The first connector includes a pump-handle lock (110) for engaging a ramped boss (120) of the second connector. The pump-handle lock features a beam seat (112) for receiving a distal end portion (106a) of the cantilever beam, wherein the distal end (106b) thereof has a lip (140). The first connector further includes left and right rear guide tabs (114, 116) which abut opposing left and right end walls (126, 128) of the cut-out, as well as left and right forward guide tabs (162, 164) for respectively engaging left and right tab collets (122, 124) of the second connector.
