1. A connector assembly for transferring fluids from one source to another under contaminant precluding conditions, includinga first connector having one end for conduit connection to a fluid source and an opposite open end, a first tubular coupling element positioned within said first connector, said first tubular coupling element being communicable with said conduit connection, a penetrating end associated with said first tubular coupling element,a second connector having one end for conduit connection to a fluid source and an opposite open end, a second tubular coupling element positioned within said second connector, said second tubular coupling element being communicable with said conduit connection, said second tubular coupling element having an end engageable with said first tubular coupling element,a penetratable barrier assembly closing the open end of each of the connectors, each barrier assembly including a penetratable barrier and a removable protective member, an adhesive film covering a substantial portion of the area between the barrier and the protective member in at least one of said barrier assemblies, said protective member having a barrier portion covering the penetratable barrier, and a handle portion folded over the barrier portion and extending beyond the connector, said handle portions progressively exposing said adhesive film upon being pulled to progressively adhere the protective barriers to each other, andmeans to permit relative movement between the penetrating end and the adjoined barriers so that said penetrating end moves through said area of adhesion, said first coupling element engages said second coupling element to establish a fluid path after the adhered barriers are penetrated, said fluid moving through said engaged coupling elements without contacting the penetrated barriers on the penetrating end.
