A ball chain connector for use with ball chains having a series of balls connected together by flexible member sections and for connecting together two ball chain ends, the ball chain connector including: a first part and a second part; wherein: the first part defines a first cavity for receiving an end ball at the end of a ball chain and a first through hole for passing a flexible member section of the ball chain; the second part defines a second cavity for receiving an end ball at the end of a ball chain and a second through hole for passing a flexible member section of the ball chain; the first part includes a ball-shaped connector at the distal end of a stem extending opposite to said first through hole; the second part includes at least one resilient wall opposite said second through hole configured to receive and resiliently hold said ball-shaped connector and configured to define a connection aperture from which, when fitted, said stem extends; and said resilient wall is configured to be resiliently deflected so as to release the ball-shaped connector and allow the first and second parts (32, 34) to separate, characterized in that said resilient wall defines a side opening, between the second through hole and the connection aperture, into which said ball-shaped connector can be inserted. a first part and a second part; wherein: the first part defines a first cavity for receiving an end ball at the end of a ball chain and a first through hole for passing a flexible member section of the ball chain; the second part defines a second cavity for receiving an end ball at the end of a ball chain and a second through hole for passing a flexible member section of the ball chain; the first part includes a ball-shaped connector at the distal end of a stem extending opposite to said first through hole; the second part includes at least one resilient wall opposite said second through hole configured to receive and resiliently hold said ball-shaped connector and configured to define a connection aperture from which, when fitted, said stem extends; and said resilient wall is configured to be resiliently deflected so as to release the ball-shaped connector and allow the first and second parts (32, 34) to separate, characterized in that said resilient wall defines a side opening, between the second through hole and the connection aperture, into which said ball-shaped connector can be inserted. the first part defines a first cavity for receiving an end ball at the end of a ball chain and a first through hole for passing a flexible member section of the ball chain; the second part defines a second cavity for receiving an end ball at the end of a ball chain and a second through hole for passing a flexible member section of the ball chain; the first part includes a ball-shaped connector at the distal end of a stem extending opposite to said first through hole; the second part includes at least one resilient wall opposite said second through hole configured to receive and resiliently hold said ball-shaped connector and configured to define a connection aperture from which, when fitted, said stem extends; and said resilient wall is configured to be resiliently deflected so as to release the ball-shaped connector and allow the first and second parts (32, 34) to separate, characterized in that said resilient wall defines a side opening, between the second through hole and the connection aperture, into which said ball-shaped connector can be inserted.
