System for securing a sign to a support surface

A system for securing a sign to a support surface, said system comprising:

• a sign-carrying part for releasable attachment on a mounting part, said sign-carrying part having a front side for holding the sign and a back side provided with a track that loosely holds a locking plate, said track providing a compartment for the locking plate with an opening distal to the back side of the sign-carrying part, said locking plate provided with a protrusion that protrudes beyond the opening of the track when the locking plate is resting on the inner surface of the track distal to the back side;
• the mounting part configured to be fixedly attached to a support surface, said mounting part having a backside for mounting it on the support surface, and a front side with a track for receiving the protrusion of the locking plate thereby preventing lateral displacement/movement transversally in relation to the track of the sign-carrying part;
• wherein the mounting part and the sign-carrying part further comprise mutually cooperating profile portions, said locking plate being magnetic and in an a locking position when not being influenced by an external magnetic force from the front side of the sign that is greater than the magnetic force between the locking plate and a part of the front side of the mounting part, said locking plate being in an open position when influenced by said external magnetic force thereby allowing the sign-carrying part to be released from said mounting part.
