A releasable fastening arrangement

A first unit including a first member of a releasable fastening arrangement arranged for providing:

• a mechanical connection of said first unit to a second unit;
• and
• an electrical connection of a first electrical circuit included in said first unit to a second electrical circuit included in said second unit;
• wherein:
• said first member has at least one male profile, said at least one male profile including one or more at least partially resilient latching arm members arranged for engaging with one or more corresponding slots of at least one corresponding female profile included in a second member of said second unit when said at least one male profile is inserted into said at least one female profile, whereby said mechanical connection is provided;
• and
• said first electrical circuit has at least one first portion, said at least one first portion including one or more first flexible conductors arranged on at least one side of a first flexible and electrically insulating layer, and being arranged between said at least one male profile and said at least one female profile together with a corresponding at least one second portion of said second electrical circuit, said at least one second portion including one or more second flexible conductors arranged on at least one side of a second flexible and electrically insulating layer, whereby said electrical connection is provided by contact between said one or more first flexible conductors and said one or more second flexible conductors when said at least one male profile is inserted into said at least one female profile.
