biases the tabs 84 toward the first lower position as shown in fig5 the spring 80 washer 82 and tabs 84 are enclosed in a spring connector cover 88 which is held in position by snap ring 90 which engages annular groove 78 as most clearly shown in fig5 when the male connector 42 and the female connector 56 are connected by engagement of projections 86 with groove 44 the upper portion of tube 45 extends beyond o ring 70 thus the o ring 70 forms a seal between the outside wall of tube 45 and the inside wall of the main female body portion 65 also since since groove 44 extends around the outer circumference of tube 45 the projections 86 will engage the groove 44 and the o ring 70 will perform its sealing function while the female connector 56 is freely rotatable to any position in operation the horizontal member of tee 58 at the inlet fitting 16 is connected to an automatic film processor by plastic tubing not shown the spent fixer solution 90 is gravity fed into the filter 10 the solution 90 enters the canister 12 through tube 52 and passes through filter element 24 the silver ions in the fixer solution are attached to and built up onto the outside of the wire filter.
