Wound therapy device

A wound therapy device, comprising

• an outer part comprising a connector opening adapted to be connected to an external device, said outer part being adapted to be at least partially located on a first side of a wound cover film,
• an inner part adapted to be at least partially located on a second side of said wound cover film, wherein said second side is opposite of said first side of said wound cover film,
• said wound therapy device being such that said outer part and said inner part are adapted to be attached to one another, by means of a locking means of said wound therapy device, with said wound cover film arranged therebetween and such that said connector opening is in fluid communication with a wound therapy volume that is at least partially delimited by said second side of said wound cover film,
• wherein said locking means comprises a snap-on connection comprising an elastically deformable protrusion connected to said outer part, at least a portion of said snap-on connection being adapted to be located on said first side of said wound cover film when said locking means attaches said outer part to said inner part,
• wherein said wound therapy device is adapted to be used for a wound area that has an extension in a wound extension plane (Pwe), said locking means being such that said outer part is adapted to be attached to said inner part by displacing the outer part relative to the inner part in a rectilinear direction that is substantially parallel to a direction in said wound extension plane (Pwe).
