A connector assembly for connecting medical lines (3, 4) to each other comprises a first connector (1) having an insertion shaft (12), and a second connector (2) having an insertion opening (22). For connecting the first connector (1) and the second connector (2) to each other, the insertion shaft (12) of the first connector (1) is insertable along an insertion direction (I) into the insertion opening (22) of the second connector (2). For releasing the first connector (1) and the second connector (2) from each other, the insertion shaft (12) of the first connector (1) is removable from the insertion opening (22) of the second connector (2). The first connector (1) comprises an elastic member (14) arranged on the insertion shaft (12), wherein the elastic member (14) comprises an abutment portion (141) abutting a surface (121) of the insertion shaft (12) and being displaceable along the insertion direction (I) relative to the surface (121) of the insertion shaft (12) upon releasing the first connector (1) and the second connector (2) from each other. In this way a connector assembly is provided which, in an easy way, allows for the cleaning of at least the first connector.Un ensemble raccord permettant de raccorder des lignes médicales (3, 4) l'une à l'autre comprend un premier raccord (1) ayant un arbre d'insertion (12), et un second raccord (2) ayant une ouverture d'insertion (22). Pour raccorder le premier raccord (1) et le second raccord (2) l'un à l'autre, l'arbre d'insertion (12) du premier raccord (1) peut être inséré le long d'une direction d'insertion (I) dans l'ouverture d'insertion (22) du second raccord (2). Pour libérer le premier raccord (1) et le second raccord (2) l'un de l'autre, l'arbre d'insertion (12) du premier raccord (1) peut être retiré de l'ouverture d'insertion (22) du second raccord (2). Le premier raccord (1) comprend un élément élastique (14) disposé sur l'arbre d'insertion (12), l'élément élastique (14) comprenant une partie de butée (141
